|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,

|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "[]"
|
||||
replaced with your own identifying information. (Don't include

||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||
same "printed page" as the copyright notice for easier

<h2>Directives</h2>
|
||||
<p>
|
||||
The module is configured by directives. All directives process the
|
||||
connection, HTTP request, and response data in a pre-defined sequence.
|
||||
The following graph shows the order in which the directives work.
|
||||

<a name="rules"></a>
|
||||
<h2>Rules</h2>
|
||||
<p>
|
||||
<a href="index.html">mod_qos</a> allows you to configure different kind of
|
||||
rules. The main component of a rule is its counter. A rule measures either
|
||||
the <a href="#concurrency">concurrency</a> (how many times something happens
|
||||
at the same time), the <a href="#repeat">occurrence </a> (how often does
|
||||
something happen in a certain amount of time), or the
|
||||
<a href="#throughput">throughput</a> (sent amount of data or number of
|
||||
request) and stores this information within that counter.</p>
|
||||
<p>
|
||||
Every rule has it's own threshold and maintains its own counter. A rule
|
||||
is identified by either an URL pattern/matching string or by an
|
||||
<a href="#variables">environment variable name</a>.
|
||||
You can configure as many rules as you want. </p>
|
||||
<img src="images/Rule.png" height="164" width="514" alt="Rule" />
|
||||
<p>
|
||||
<i>Note: Some counters are only available once. This applies to the counters of
|
||||
the rules using the
|
||||
<code><a href="index.html#QS_Block">QS_Block</a></code>,
|
||||
<code><a href="index.html#QS_SrvSerialize_var">QS_SrvSerialize</a></code>, and

<a name="variables"></a>
|
||||
<h2>Environment Variables</h2>
|
||||
<p>
|
||||
The Apache web server provides a mechanism for storing information
|
||||
in so called <i>environment variables</i>. <a href="index.html">mod_qos</a> uses these
|
||||
variables to exchange data respectively signalize events between
|
||||
<a href="#rules">different rules</a> defined by the
|
||||
<a href="#directives">corresponding directive</a>. These
|
||||
variables can also be written or read by other Apache modules, such as
|
||||
<a href="http://modsetenvifplus.sourceforge.net/">mod_setenvifplus <img src="images/link.png"/></a>
|
||||
or <a href="http://httpd.apache.org/docs/current/mod/mod_setenvif.html">mod_setenvif <img src="images/link.png"/></a>.
|
||||
</p>
|
||||
<p>Example:<br>
|
||||
The <code><a href="http://httpd.apache.org/docs/current/mod/mod_setenvif.html#setenvif">SetEnvIf <img src="images/link.png"/></a></code> directive
|
||||
is used to set the <i>LimitLogin</i> variable if the request line matches
|
||||
the <code>^/wp-login.php</code> pattern while the
|
||||
<a href="index.html#QS_ClientEventLimitCount"><code>QS_ClientEventLimitCount</code></a>
|
||||
directives increments the <a href="#repeat">repeat counter</a> having the same name
|
||||
if the variable is present.
|
||||
<br>
|
||||
<img src="images/Events.png" height="396" width="795" alt="Event set by SetEnvIf and processed by QS_ClientEventLimitCount" />
|
||||
</p>
|
||||
<p>It is also possible to write the values of these variables to your log
|
||||
file using the format string <code>%{VARNAME}e</code> within the
|
||||
<code><a href="http://httpd.apache.org/docs/current/mod/mod_log_config.html">TransferLog/CustomLog <img src="images/link.png"/></a></code>
|
||||
directives. Or you can use them within error pages using
|
||||
<a href="#ssi">server-side includes (SSI)</a>.
|
||||
</p>
|
||||
<p>
|
||||
<i>Note: Whenever you use a directive (such as
|
||||
<code><a href="http://modsetenvifplus.sourceforge.net/#SetEnvIfPlus">SetEnvIfPlus <img src="images/link.png"/></a></code>) which can either process request attributes (such
|
||||
as HTTP headers) or environment variables, you must make sure that
|
||||
a client can not bypass your rules by sending a request header
|
||||
with the same name as the environment variable used in your configuration.
|
||||
Use either the <a href="index.html#QS_RequestHeaderFilter">request header filter</a>
|
||||
or the <code><a href="index.html#QS_UnsetReqHeader">QS_UnsetReqHeader</a></code>
|
||||
directive to prevent anyone from sending a request header with the same name as
|
||||
the variable you have defined.
|
||||

<a name="concurrency"></a>
|
||||
<h2>Concurrency Counter</h2>
|
||||
<p>
|
||||
A "concurrency counter" is used to determine how many times something
|
||||
happens at the same time (concurrent), e.g. HTTP requests accessing the same
|
||||
resource/URL at the same time. The rules using this counter type are either
|
||||
defined by an <a href="#variables">environment variable name</a> or an
|
||||
URL pattern (regular expression or a string matching the request's URL).
|
||||
Such a rule automatically increments the counter when the Apache web server
|
||||
starts to process a matching request and decrements the counter when the
|
||||
request processing is completed.
|
||||
</p>
|
||||
<p>
|
||||
You have to configure a threshold and the rule's variable name resp. URL
|
||||
pattern. Requests (or new connections) are denied as soon as the configured
|
||||
threshold is reached.
|
||||
</p>
|
||||
<p>
|
||||
Directives using this counter type are:
|
||||
<ul>
|
||||
<li><a href="index.html#QS_LocRequestLimitMatch"><syntax>QS_LocRequestLimitMatch</syntax></a></li>
|
||||
<li><a href="index.html#QS_LocRequestLimit"><syntax>QS_LocRequestLimit</syntax></a></li>
|
||||
<li><a href="index.html#QS_CondLocRequestLimitMatch"><syntax>QS_CondLocRequestLimitMatch</syntax></a></li>
|
||||
<li><a href="index.html#QS_EventRequestLimit"><syntax>QS_EventRequestLimit</syntax></a></li>
|
||||
<li><a href="index.html#QS_ClientEventRequestLimit"><syntax>QS_ClientEventRequestLimit</syntax></a></li>
|
||||
</ul>
|
||||
Also the
|
||||
<a href="index.html#QS_SrvMaxConn"><code>QS_SrvMaxConn</code></a>,
|
||||
<a href="index.html#QS_SrvMaxConnClose"><code>QS_SrvMaxConnClose</code></a>, and
|
||||
<a href="index.html#QS_SrvMaxConnPerIP"><code>QS_SrvMaxConnPerIP</code></a>
|
||||
directives use this counter type, although with fewer parameter options.
|
||||
</p>
|
||||
<p>
|
||||
<a name="QS_LocRequestLimit_Example"></a>
|
||||
<h4>Sample Use Case</h4>
|
||||
Now let us look at an example to show where these rules can be used.
|
||||
Let's assume that you have two applications. We call them
|
||||
"<font color="green">A</font>" and "<font color="blue">B</font>".
|
||||
Application "<font color="green">A</font>" has been deployed on
|
||||
path <code>/app/a</code> and "<font color="blue">B</font>"
|
||||
on <code>/app/b</code>.
|
||||
<table width="780px">
|
||||
<tr>
|
||||
<td> </td>
|
||||
<td>
|
||||
As long as the server has enough resources, users can access both
|
||||
applications the same time without influencing each other.<br>
|
||||
All requests are processed quickly and the workers (w) become free
|
||||
again to serve new requests.
|
||||
<br><br>
|
||||
</td>
|
||||
<td>
|
||||
<small> </small> <img src="images/qsloc1.png" height="216" width="408" alt="trouble-free"/>
|
||||
</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td> </td>
|
||||
<td>
|
||||
But if the application "<font color="blue">B</font>" becomes slow,
|
||||
the duration of request processing increases and all workers (w) become busy.
|
||||
There are no free workers left and application
|
||||
"<font color="green">A</font>" becomes unavailable because of that.
|
||||
<br><br>
|
||||
</td>
|
||||
<td>
|
||||
<img src="images/qsloc2.png" height="212" width="422" alt="disruption"/>
|
||||
</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td> </td>
|
||||
<td>
|
||||
A <a href="index.html#QS_LocRequestLimit"><code>QS_LocRequestLimit</code></a> or
|
||||
<a href="index.html#QS_LocRequestLimitMatch"><code>QS_LocRequestLimitMatch</code></a>
|
||||
rule can help in such a situation. mod_qos limits the
|
||||
number of requests to application "<font color="blue">B</font>"
|
||||
so that application "<font color="green">A</font>" remains
|
||||
available even if application "<font color="blue">B</font>"
|
||||
has performance problems.
|
||||
</td>
|
||||
<td>
|
||||
<img src="images/qsloc3.png" height="244" width="422" alt="disruption"/>
|
||||
</td>
|
||||
</tr>
|
||||
</table>
|
||||
<br>
|
||||
Such a scenario can occur due to various infrastructure problems,
|
||||
e.g., by slow database queries.<br> A similar situation can also
|
||||
arise through an external influence: if someone penetrates application
|
||||
"<font color="blue">B</font>" with a <i>HTTP GET / POST flood DoS attack</i>,
|
||||
then application "<font color="green">A</font>" could also become
|
||||
unreachable.
|
||||
A <a href="index.html#QS_LocRequestLimit"><code>QS_LocRequestLimit</code></a>
|
||||
rule can prevent this.
|
||||

<a name="repeat"></a>
|
||||
<h2>Repeat Counter</h2>
|
||||
<p>
|
||||
"Repeat counters" limit the number how often (Cr) something is allowed to
|
||||
happen in a certain amount of time (Td). These rules trigger a timer whenever
|
||||
the defined event occurs the first time and start to count every subsequent event
|
||||
until the timer expires. If the event counter reaches the defined limitation,
|
||||
requests are blocked until the time is up.
|
||||
</p>
|
||||
<p>
|
||||
<img src="images/LimitCount.png" height="432" width="576" alt="reapet counter"/>
|
||||
</p>
|
||||
<p>
|
||||
All repeat counters allow you to define an event which shall
|
||||
increment the counter if they occur. You also have to configure a
|
||||
duration Td and the threshold Cr, defining how many events are
|
||||
allowed within the time Td.</p>
|
||||
<p>Directive parameter example:<br>
|
||||
<img src="images/LimitCountExample.png" height="165" width="574" alt="QS_ClientEventLimitCount" />
|
||||
</p>
|
||||
<p>
|
||||
While the counter is automatically cleared (set to 0) when the
|
||||
time Td is up, you might also configure additional events to
|
||||
<a href="index.html#_Decrement">decrement</a> or
|
||||
<a href="index.html#_Clear">clear</a> the counter earlier.
|
||||
</p>
|
||||
<p>
|
||||
The directives using this counter type are:
|
||||
<ul>
|
||||
<li><a href="index.html#QS_EventLimitCount"><syntax>QS_EventLimitCount</syntax></a></li>
|
||||
<li><a href="index.html#QS_CondEventLimitCount"><syntax>QS_CondEventLimitCount</syntax></a></li>

|
||||
<li><a href="index.html#QS_ClientEventBlockCount"><syntax>QS_ClientEventBlockCount</syntax></a></li>
|
||||
</ul>
|
||||
<i>Note: Some directives support the increase of the counter by more than "1"
|
||||
taking the variable's value into account.</i>

<h2>Throughput Control</h2>

<p>
|

Throughput control is implemented by measuring the current usage and

data processing in order to achieve the desired limitation (closed

<h3>Requests per Second</h3>
|

<p>
|

It is also possible to limit the number or requests per second to a

resource. This control function is less accurate than the bandwidth
|
||||
limitation, since the measurement of the request rate takes longer
|
||||
(several seconds) and the request delay is more coarse-grained.<br>
|
||||
The following directive can be used to limit the number of requests
|
||||
per second:

<h2>Serialization</h2>
|
||||
<p>
|
||||
<a href="index.html">mod_qos</a> offers you the option to serialize requests.
|
||||
Serialization means, that requests are processed one after the other. Incoming
|
||||
requests are queued if another request is in process and have to wait until
|
||||
the previous request is finished.
|
||||
</p>
|
||||
<p>
|
||||
<img src="images/Serialization.png" height="336" width="570" alt="serialization"/>
|
||||
</p>
|
||||
<p>
|
||||
Requests, which shall be serialized, are tagged by one of the following
|
||||
<a href="#variables">environment variables</a>:
|
||||
<ul>
|
||||
<li><syntax><a href="index.html#QS_SrvSerialize_var">QS_SrvSerialize</a></syntax></li>
|
||||
<li><syntax><a href="index.html#QS_Serialize">QS_Serialize</a></syntax></li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
Serialization might be applied on a per
|
||||
<a href="index.html#QS_SrvSerialize">server level</a> (serializing all HTTP
|
||||
requests) or on a <a href="index.html#QS_ClientSerialize">per client level</a>
|
||||
(serializing multiple requests coming from the same client/IP address).

<h2>User Tracking</h2>
|
||||
<p>
|
||||
It might be necessary to identify individual users to define appropriate QoS
|
||||
rules. For this reason, <a href="index.html">mod_qos</a> can set a cookie
|
||||
containing a unique identifier. This identifier is then written to the
|
||||
<code><a href="index.html#mod_qos_user_id">mod_qos_user_id</a></code>
|
||||
environment variable and you can add it to your log files by the
|
||||
format string <code>%{mod_qos_user_id}e</code>. This allows you to identify
|
||||
all requests issued by a user.</p>
|
||||
<p>
|
||||
This feature is enabled by the following directive:
|
||||
<ul>
|
||||
<li><syntax>QS_UserTrackingCookieName <name> [<path>] [<domain>] ['session'] ['jsredirect']</syntax><br>
|
||||
The parameter "name" defines the cookie's name and "domain" (optional)
|
||||
the domain attribute for the Set-Cookie header. The string "session" can
|
||||
be defined if the cookie should not be stored by the session (but can
|
||||
be deleted when the user closes this browser).
|
||||
</li>
|
||||
</ul>
|
||||
You can also enforce the browser to support cookies by specifying the
|
||||
"path" parameter for the <code>QS_UserTrackingCookieName</code> directive.
|
||||
This parameter defines an error document and mod_qos
|
||||
answers the request with a redirect (302) to this document when setting
|
||||
the cookie initially. The browser will follow the redirect and mod_qos
|
||||
redirects the browser back to the initially requested page if the request
|
||||
to this error document contains the tracking cookie. If the browser did not
|
||||
send the cookie, the error document is shown.

||||

<h2>Request Statistics Using <i>qslog</i></h2>
|

<p>
|

<code><a href="qslog.1.html">qslog</a></code> is a command line tool to
|
||||
generate usage statistics data from log files. It can generate the data in
|
||||
real time if defined within your Apache's server configuration.

Or you can use it to process any existing log file using the post processing

option <code>-p</code>. This does not only work for
|
||||
<a href="http://httpd.apache.org/docs/current/mod/mod_log_config.html">Apache log <img src="images/link.png"/></a> files but for any other log file as well. You just have to know what's in the log
|

and configure the format string argument <code>-f</code> of the
|
||||
<code><a href="qslog.1.html">qslog</a></code> command accordingly.

The output shows the data as a function of time: a summary of what happened every minute.

Each line includes all measured values as semicolon spearated name/value pairs (CSV).

<H2>DESCRIPTION</H2>
|
||||
|
||||
qsdt is a simple tool to search two different messages in a log file and calculates the elapsed time between these lines. The two log messages need a common identifier such an unique request id (UNIQUE_ID), a thread id, or a transaction code.
|
||||
<A NAME="lbAE"> </A>
|
||||
<H2>OPTIONS</H2>
|
||||
|
||||
<DL COMPACT>
|
||||
<DT>-t <regex> <DD>
|
||||
Defines a pattern (regular expression) matching the log line's timestamp. The pattern must include two sub-expressions, one matching hours, minutes and seconds the other matching the milliseconds. Default pattern is ([0-9]{2}:[0-9]{2}:[0-9]{2})[.,]([0-9]{3})
|
||||
<DT>-i <regex> <DD>
|
||||
Pattern (regular expression) matching the identifier which the two messages have in common. The sub-expression defines the part which needs to be extracted from the matching string. Note: You can also use the start (-s) and end (-e) pattern to define the sub-expression matching this identifier.
|
||||
<DT>-s <regex> <DD>
|
||||
Defines the pattern (regular expression or literal string) identifying the first (start) of the two messages.
|
||||
<DT>-e <regex> <DD>
|
||||
Defines the pattern (regular expression or literal string) identifying the second (end) of the two messages.
|
||||
<DT>-v <DD>
|
||||
Verbose mode.
|
||||
<DT><path> <DD>
|
||||
Defines the input file to process. qsdt reads from from standard input if this parameter is omitted.
|
||||

|

<A NAME="lbAF"> </A>
|
||||
<H2>EXAMPLE</H2>
|
||||
|
||||
Sample command line arguments:
|
||||
<P>
|
||||
<BR> -i ' ([a-z0-9]+) [A-Z]+ ' -s 'Received Request' -e 'Received Response'
|
||||
<P>
|
||||
<BR> matching those sample log messages:
|
||||
<BR> 2018-03-12 16:34:08.653 threadid23 INFO Received Request
|
||||
<BR> 2018-03-13 16:35:09.891 threadid23 DEBUG MessageHandler Received Response
|
||||
<P>
|
||||
<A NAME="lbAG"> </A>
|
||||
<H2>NOTE</H2>
|
||||
|
||||
The four patterns (t,i,s,e) are concatenated into two search patterns:
|
||||
<BR> first (start): [t (HH:MM:SS)(SSS) ].*[i (id) ].*[s ]
|
||||
<BR> second (end): [t (HH:MM:SS)(SSS) ].*[i (id) ].*[e ]
|
||||
<P>
|
||||
And the three sub-expression are used to extract the timestamp and the unique identifier that the start and end message have in common. This means that you could specify the sub-expression for the unique identifier in the start (-s) or end (-e) pattern alternatively, e.g. in case the identifier is at the end of the log line.

qsfilter2 - an utility to generate mod_qos request line rules out from existing access/audit log data.
|
||||
<A NAME="lbAC"> </A>
|
||||
<H2>SYNOPSIS</H2>
|
||||
|
||||
qsfilter2 -i <path> [-c <path>] [-d <num>] [-h] [-b <num>] [-p|-s|-m|-o] [-l <len>] [-n] [-e] [-u 'uni'] [-k <prefix>] [-t] [-f <path>] [-v 0|1|2]

|

<H2>DESCRIPTION</H2><p><img src="qsfilter2_process.gif" alt="overview"></p>
|
||||
|
||||
mod_qos implements a request filter which validates each request line. The module supports both, negative and positive security model. The QS_Deny* directives are used to specify request line patterns which are not allowed to access the server (negative security model / deny list). These rules are used to restrict access to certain resources which should not be available to users or to protect the server from malicious patterns. The QS_Permit* rules implement a positive security model (allow list). These directives are used to define allowed request line patterns. Request which do not match any of these patterns are not allowed to access the server.
|
||||
<P>
|
||||
qsfilter2 is an audit log analyzer used to generate filter rules (perl compatible regular expressions) which may be used by mod_qos to deny access for suspect requests (QS_PermitUri rules). It parses existing audit log files in order to generate request patterns covering all allowed requests.
|
||||
<A NAME="lbAE"> </A>
|
||||
<H2>OPTIONS</H2>
|
||||
|
||||
<DL COMPACT>
|
||||
<DT>-i <path> <DD>
|
||||
Input file containing request URIs. The URIs for this file have to be extracted from the servers access logs. Each line of the input file contains a request URI consisting of a path and and query.
|
||||
<BR> Example:
|
||||
<BR> /aaa/index.do
|
||||
<BR> /aaa/edit?image=1.jpg
|
||||
<BR> /aaa/image/1.jpg
|
||||
<BR> /aaa/view?page=1
|
||||
<BR> /aaa/edit?document=1
|
||||
<P>
|
||||
These access log data must include current request URIs but also request lines from previous rule generation steps. It must also include request lines which cover manually generated rules. You may use the 'qos-path' and 'qos-query' variables to create an audit log containing all request data (path and query/body data). Example: 'CustomLog audit_log %{qos-path}n%{qos-query}n'. See also <A HREF="http://mod-qos.sourceforge.net#qsfiltersample">http://mod-qos.sourceforge.net#qsfiltersample</A> about the module settings.
|
||||
<DT>-c <path> <DD>
|
||||
mod_qos configuration file defining QS_DenyRequestLine and QS_PermitUri directives. qsfilter2 generates rules from access log data automatically. Manually generated rules (QS_PermitUri) may be provided from this file. Note: each manual rule must be represented by a request URI in the input data (-i) in order to make sure not to be deleted by the rule optimisation algorithm. QS_Deny* rules from this file are used to filter request lines which should not be used for allow list rule generation.
|
||||
<BR> Example:
|
||||
<BR> # manually defined allow list rule:
|
||||
<BR> QS_PermitUri +view deny "^[/a-zA-Z0-9]+/view\?(page=[0-9]+)?$"
|
||||
<BR> # filter unwanted request line patterns:
|
||||
<BR> QS_DenyRequestLine +printable deny ".*[\x00-\x19].*"
|
||||
<P>
|
||||
<P>
|
||||
<DT>-d <num> <DD>
|
||||
Depth (sub locations) of the path string which is defined as a literal string. Default is 1.
|
||||
<DT>-h <DD>
|
||||
Always use a string representing the handler name in the path even the url does not have a query. See also -d option.
|
||||
<DT>-b <num> <DD>
|
||||
Replaces url pattern by the regular expression when detecting a base64/hex encoded string. Detecting sensibility is defined by a numeric value. You should use values higher than 5 (default) or 0 to disable this function.
|
||||
<DT>-p <DD>
|
||||
Represents query by pcre only (no literal strings).
|
||||
<DT>-s <DD>
|
||||
Uses one single pcre for the whole query string.
|
||||
<DT>-m <DD>
|
||||
Uses one pcre for multiple query values (recommended mode).
|
||||
<DT>-o <DD>
|
||||
Does not care the order of query parameters.
|
||||
<DT>-l <len> <DD>
|
||||
Outsizes the query length by the defined length ({0,size+len}), default is 10.
|
||||
<DT>-n <DD>
|
||||
Disables redundant rules elimination.
|
||||
<DT>-e <DD>
|
||||
Exit on error.
|
||||
<DT>-u 'uni' <DD>
|
||||
Enables additional decoding methods. Use the same settings as you have used for the QS_Decoding directive.
|
||||
<DT>-k <prefix> <DD>
|
||||
Prefix used to generate rule identifiers (QSF by default).
|
||||
<DT>-t <DD>
|
||||
Calculates the maximal latency per request (worst case) using the generated rules.
|
||||
<DT>-f <path> <DD>
|
||||
Filters the input by the provided path (prefix) only processing matching lines.
|
||||
<DT>-v <level> <DD>
|
||||
Verbose mode. (0=silent, 1=rule source, 2=detailed). Default is 1. Don't use rules you haven't checked the request data used to generate it! Level 1 is highly recommended (as long as you don't have created the log data using your own web crawler).

|

<H2>OUTPUT</H2>
|
||||
|
||||
The output of qsfilter2 is written to stdout. The output contains the generated QS_PermitUri directives but also information about the source which has been used to generate these rules. It is very important to check the validity of each request line which has been used to calculate the QS_PermitUri rules. Each request line which has been used to generate a new rule is shown in the output prefixed by "ADD line <line number>:". These request lines should be stored and reused at any later rule generation (add them to the URI input file). The subsequent line shows the generated rule. At the end of data processing a list of all generated QS_PermitUri rules is shown. These directives may be used withn the configuration file used by mod_qos.

<P>
|
||||
<DT>-o <out_file> <DD>
|
||||
Specifies the file to store the output to. stdout is used if this option is not defined.
|
||||
<DT>-p <DD>
|
||||
Used for post processing when reading the log data from a file (cat/pipe). qslog is started using it's offline mode (extracting the time stamps from the log lines) in order to process existing log files. The option "-pc" may be used alternatively if you want to gather request information per client (identified by IP address (I) or user tracking id (U) showing how many request each client has performed within the captured period of time). "-pc" supports the format characters IURSBTtDkMEcm. The option "-pu" collects statistics on a per URL level (supports format characters RSTtD). "-puc" is very similar to "-pu" but cuts the end (handler) of each URL.
|
||||
<DT>-v <DD>
|
||||
Verbose mode.
|
||||
<DT>-x [<num>] <DD>
|
||||
Rotates the output file once a day (move). You may specify the number of rotated files to keep. Default are 14.
|
||||
<DT>-u <name> <DD>
|
||||
Becomes another user, e.g. www-data.
|
||||
<DT>-m <DD>
|
||||
Calculates free system memory every minute.
|
||||
<DT>-c <path> <DD>
|
||||
Enables the collection of log statistics for different request types. 'path' specifies the necessary rule file. Each rule consists of a rule identifier and a regular expression to identify a request seprarated by a colon, e.g., 01:^(/a)|(/c). The regular expressions are matched against the log data element which has been identified by the 'C' format character.

The following environment variables are known to qslog:
|
||||
<DL COMPACT>
|
||||
<DT>QSEVENTPATH=<path> <DD>
|
||||
Defines a file containing a comma or new line separated list of known event strings expected within the log filed identified by the 'E' format character.
|
||||
<DT>QSCOUNTERPATH=<path> <DD>
|
||||
Defines a file containing a by new line separated list of rules which reflect possible QS_ClientEventLimitCount directive settings (for simulation purpose / -pc option). The 'E' format character defines the event string in the log to match (literal string) the 'event1' and 'event2' event names against.
|
||||
<P>
|
||||
Rule syntax: <name>:<event1>-<n>*<event2>/<duration>=<limit>
|
||||
<BR> 'name' defines the name you have given to the rule entry and is logged along with
|
||||
with the number of times the 'limit' has been reached within the 'duration'.
|
||||
<BR> 'event1' defines the variable name (if found in 'E') to increment the counter.
|
||||
<BR> 'event2' defines the variable name (if found in 'E') to decrement the counter (and
|
||||
the parameter 'n' defines by how much).
|
||||
<BR> 'duration' defines the measure interval (in seconds) used for the
|
||||
QS_ClientEventLimitCount directive.
|
||||
<BR> 'limit' defines the threshold (number) defined for the QS_ClientEventLimitCount
|
||||
directive.
|
||||
<P>
|
||||
Note: If the 'name' parameter is prefixed by 'STATUS', the rule is applied against the HTTP status code 'S' and the 'event1' string shall contain a list of relevant status codes separated by an underscore (while 'event2' is ignored).

|
||||
## -MM, not -M (despite what the docs say). Also, it might not be
|
||||
## supported by the other compilers which use the 'gcc' depmode.

## This next piece of magic avoids the "deleted header file" problem.
|
||||
## The problem is that when a header file which appears in a .P file
|
||||
## is deleted, the dependency causes make to die (because there is
|
||||
## typically no way to rebuild the header). We avoid this by adding
|
||||
## dummy dependencies for each header file. Too bad gcc doesn't do
|
||||
## this for us directly.
|
||||
## Some versions of gcc put a space before the ':'. On the theory
|
||||
## that the space means something, we add a space to the output as
|
||||
## well. hp depmode also adds that space, but also prefixes the VPATH
|
||||
## to the object. Take care to not repeat it in the output.

## Some versions of the HPUX 10.20 sed can't process this invocation

## correctly. Breaking it into two sed invocations is a workaround.

.SH NAME
|
||||
mod_qos \- quality of service module for the Apache Web server
|
||||
.SH DESCRIPTION
|
||||
mod_qos is a quality of service module for the Apache web server implementing control mechanisms that can provide different levels of priority to different HTTP requests.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
QS_LocRequestLimitDefault <number>, defines the default for the QS_LocRequestLimit and QS_LocRequestLimitMatch directive.
|
||||
.TP
|
||||
QS_LocRequestLimit <location> <number>, defines the maximum number of concurrent requests allowed to access the specified location. Default is defined by the QS_LocRequestLimitDefault directive.
|
||||
.TP
|
||||
QS_LocRequestPerSecLimit <location> <number>, defines the allowed number of requests per second to a location. Requests are limited by adding a delay to each requests. This directive should be used in conjunction with QS_LocRequestLimit only.
|
||||
.TP
|
||||
QS_LocKBytesPerSecLimit <location> <kbytes>, defines the allowed download bandwidth to the defined kbytes per second. Responses areslowed by adding a delay to each response (non\-linear, bigger files get longer delay than smaller ones). This directive should be used in conjunction with QS_LocRequestLimit only.
|
||||
.TP
|
||||
QS_LocRequestLimitMatch <regex> <number>, defines the number of concurrent requests to the uri (path and query) pattern. Default is defined by the QS_LocRequestLimitDefault directive.
|
||||
.TP
|
||||
QS_LocRequestPerSecLimitMatch <regex> <number>, defines the allowed number of requests per second to the uri (path and query) pattern. Requests are limited by adding a delay to each requests. This directive should be used in conjunction with QS_LocRequestLimitMatch only.
|
||||
.TP
|
||||
QS_LocKBytesPerSecLimitMatch <regex> <kbytes>, defines the allowed download bandwidth to the location matching the defined URL (path and query) pattern. Responses are slowed down by adding a delay to each response (non\-linear, bigger files get longer delay than smaller ones). This directive should be used in conjunction with QS_LocRequestLimitMatch only.
|
||||
.TP
|
||||
QS_CondLocRequestLimitMatch <regex> <number> <pattern>, defines the number of concurrent requests to the uri (path and query) regex. Rule is only enforced if the QS_Cond variable matches the specified pattern (regex).
|
||||
.TP
|
||||
QS_EventRequestLimit <variable>[=<regex>] <number>, defines the number of concurrent events. Directive works similar to QS_LocRequestLimit, but counts the requests having the same environment variable (and optionally matching its value, too) rather than those that have the same URL pattern.
|
||||
.TP
|
||||
QS_EventPerSecLimit [!]<variable> <number>, defines how often requests may have the defined environment variable (literal string) set. It measures the occurrences of the defined environment variable on a request per seconds level and tries to limit this occurrence to the defined number. It works similar to as QS_LocRequestPerSecLimit, but counts only the requests with the specified variable (or without it if the variable name is prefixed by a '!'). If a request matches multiple events, the rule with the lowest bandwidth is applied. Events are limited by adding a delay to each request causing an event.
|
||||
.TP
|
||||
QS_EventKBytesPerSecLimit [!]<variable> <kbytes>, throttles the download bandwidth of all requests having the defined variable set to the defined kbytes per second. Responses are slowed by adding a delay to each response (non\-linear, bigger files get longer delay than smaller ones). By default, no limitation is active. This directive should be used in conjunction with QS_EventRequestLimit only (you must use the same variable name for both directives).
|
||||
.TP
|
||||
QS_EventLimitCount <env\-variable> <number> <seconds>, defines the maximum number of events allowed within the defined time. Requests are denied when reaching this limitation for the specified time (blocked at request level).
|
||||
.TP
|
||||
QS_CondEventLimitCount <env\-variable> <number> <seconds> <pattern>, same as QS_EventLimitCount but blocks requests only if the QS_Cond variable matches the specified pattern (regex).
|
||||
.TP
|
||||
QS_SrvMaxConn <number>, defines the maximum number of concurrent TCP connections for this server (virtual host).
|
||||
.TP
|
||||
QS_SrvMaxConnClose <number>[%], defines the maximum number of concurrent TCP connections until the server disables keep\-alive for this server (closes the connection after each requests. You may specify the number of connections as a percentage of MaxClients if adding the suffix '%' to the specified value.
|
||||
.TP
|
||||
QS_SrvMaxConnPerIP <number> [<connections>], defines the maximum number of connections per source IP address for this server (virtual host). 'connections' defines the number of busy connections of the server (all virtual hosts) to enable this limitation, default is 0.
|
||||
.TP
|
||||
QS_SrvMaxConnExcludeIP <addr>, excludes an IP address or address range from being limited.
|
||||
.TP
|
||||
QS_SrvMinDataRateIgnoreVIP tells the QS_SrvMaxConnPerIP directive to ignore (if set to "on") the VIP status of clients. Default is "off", which means that QS_SrvMaxConnPerIP is disabled for VIPs.
|
||||
.TP
|
||||
QS_SrvSerialize 'on'|'off' [<seconds>], ensures that not more than one request having the QS_SrvSerialize variable set is processed at the same time by serializing them (process one after each other).
|
||||
.TP
|
||||
QS_SrvDataRateOff, disables the QS_SrvRequestRate and QS_SrvMinDataRate enforcement for a virtual host (only port/address based but not for name based virtual hosts).
|
||||
.TP
|
||||
QS_SrvRequestRate <bytes per seconds> [<max bytes per second>], defines the minimum upload throughput a client must generate. See also QS_SrvMinDataRate.
|
||||
.TP
|
||||
QS_SrvMinDataRate <bytes per seconds> [<max bytes per second> [<connections>]], defines the minimum upload/download throughput a client must generate (the bytes send/received by the client per seconds). This bandwidth is measured while transmitting the data (request line, header fields, request body, or response data). The client connection get closed if the client does not fulfill the required data rate and the IP address of the causing client get marked in order to be handled with low priority (see the QS_ClientPrefer directive). The "max bytes per second" activates dynamic minimum throughput control: The required minimal throughput is increased in parallel to the number of concurrent clients sending/receiving data. The "max bytes per second" setting is reached when the number of sending/receiving clients is equal to the MaxClients setting. The "connections" argument is used to specify the number of busy TCP connections a server must have to enable this feature (0 by default). No limitation is set by default.
|
||||
.TP
|
||||
QS_SrvMinDataRateOffEvent '+'|'\-'<env\-variable>, disables the minimal data rate enfocement (QS_SrvMinDataRate) for a certain connection if the defined environment variable has been set. The '+' prefix is used to add a variable to the configuration while the '\-' prefix is used to remove a variable.
|
||||
.TP
|
||||
QS_SrvMinDataRateIgnoreVIP tells the QS_SrvMinDataRate directive to ignore (if set to "on") the VIP status of clients. Default is "off", which means that QS_SrvMinDataRate is disabled for VIPs.
|
||||
.TP
|
||||
QS_SrvSampleRate <seconds>, defines the sampling rate used by the QS_SrvMinDataRate directive to measure the throughput of a connection.
|
||||
.TP
|
||||
QS_DenyRequestLine '+'|'\-'<id> 'log'|'deny' <regular expression>, generic request line (method, path, query and protocol) filter used to deny access for requests matching the defined regular expression. '+' adds a new rule while '\-' removes a rule for a location. The action is either 'log' (access is granted but rule match is logged) or 'deny' (access is denied).
|
||||
.TP
|
||||
QS_DenyPath, same as QS_DenyRequestLine but applied to the path only.
|
||||
.TP
|
||||
QS_DenyQuery, same as QS_DenyRequestLine but applied to the query only.
|

.TP
|

QS_DenyEvent '+'|'\-'<id> 'log'|'deny' [!]<variable>, matches requests having the defined process environment variable set (or NOT set if prefixed by a '!'). The action taken for matching rules is either 'log' (access is granted but the rule match is logged) or 'deny' (access is denied).
|
||||
.TP
|
||||
QS_PermitUri, '+'|'\-'<id> 'log'|'deny' <regular expression>, generic request filter applied to the request uri (path and query). Only requests matching at least one QS_PermitUri pattern are allowed. If a QS_PermitUri pattern has been defined an the request does not match any rule, the request is denied albeit of any server resource availability (allow list). All rules must define the same action. Regular expression is case sensitive.
|

.TP
|
||||
QS_DenyBody 'on'|'off', enabled body data filter (obsolete).
|

.TP
|
||||
QS_LimitRequestBody <bytes>, limits the allowed size of an HTTP request message body.
|
||||
.TP
|
||||
QS_DenyDecoding 'uni', enabled additional string decoding functions which are applied before matching QS_Deny* and QS_Permit* directives. Default is URL decoding (%xx, \xHH, '+').
|

.TP
|
||||
QS_DenyInheritanceOff, disable inheritance of QS_Deny* and QS_Permit* directives to a location.
|
||||
.TP
|
||||
QS_RequestHeaderFilter 'on'|'off'|'size', filters request headers by allowing only these headers which match the request header rules defined by mod_qos. Request headers which do not conform these definitions are either dropped or the whole request is denied. Custom request headers may be added by the QS_RequestHeaderFilterRule directive. Using the 'size' option, the header field max. size is verified only (similar to LimitRequestFieldsize but using individual values for each header type) while the pattern is ignored.
|
||||
.TP
|
||||
QS_ResponseHeaderFilter 'on'|'off', filters response headers by allowing only these headers which match the response header rules defined by mod_qos. Response headers which do not conform these definitions are dropped.
|
||||
.TP
|
||||
QS_RequestHeaderFilterRule <header name> 'drop'|'deny' <regular expression> <size>, used to add custom request header filter rules which override the internal filter rules of mod_qos. Directive is allowed in global server context only.
|
||||
.TP

.TP
|
||||
QS_SessionCookiePath <path>, defines the cookie path, default is "/".
|
||||
.TP
|
||||
QS_SessionTimeout <seconds>, defines the session life time for a VIP. It is only used for session based (cookie) VIP identification (not for IP based). Default is 3600 seconds.
|
||||
.TP
|
||||
QS_SessionKey <string>, secret key used for cookie encryption. Used when using the same session cookie for multiple web servers (load balancing) or sessions should survive a server restart. By default, a random key is used which changes every server restart.
|
||||
.TP
|
||||
QS_VipHeaderName <name>[=<regex>] [drop], defines an HTTP response header which marks a user as a VIP. mod_qos creates a session for this user by setting a cookie, e.g., after successful user authentication. Tests optionally its value against the provided regular expression. Specify the action 'drop' if you want mod_qos to remove this control header from the HTTP response.
|
||||
.TP
|
||||
QS_VipIPHeaderName <name>[=<regex>] [drop], defines an HTTP response header which marks a client source IP address as a VIP. Tests optionally its value against the provided regular expression. Specify the action 'drop' if you want mod_qos to remove this control header from the HTTP response.
|
||||
.TP
|
||||
QS_VipUser, creates a VIP session for users which have been authenticated by the Apache server, e.g., by the standard mod_auth* modules. It works similar to the QS_VipHeaderName directive.
|

.TP
|
||||
QS_VipIpUser, marks a source IP address as a VIP if the user has been authenticated by the Apache server, e.g. by the standard mod_auth* modules. It works similar to the QS_VipIPHeaderName directive.
|
||||
.TP
|
||||
QS_UserTrackingCookieName <name> [<path>] [<domain>] ['session'] ['jsredirect'], enables the user tracking cookie by defining a cookie name. The "path" parameter is an option cookie check page which is used to ensure the client accepts cookies. The "domain" option defines the Domain attriibute for the Set\-Cookie header. The option "session" indicates that the cookie shall be a session cookie expiring when the user closes it's browser. User tracking requires mod_unique_id. This feature is disabled by default. Ignores QS_LogOnly.
|
||||
.TP
|
||||
QS_SetEnvIf [!]<variable1>[=<regex>] [[!]<variable2>] [!]<variable=value>, sets (or unsets) the 'variable=value' (literal string) if variable1 (literal string) AND variable2 (literal string) are set in the request environment variable list (not case sensitive). This is used to combine multiple variables to a new event type. Alternatively, a regular expression can be specified for variable1's value and variable2 must be omitted in order to simply set a new variable if the regular expression matches.
|
||||
.TP
|
||||
QS_SetEnvIfCmpP <env\-variable1> eq|ne|gt|lt <env\-variable2> [!]<env\-variable>[=<value>], sets the specified environment variable if the specified env\-variables are alphabetically or numerical equal (eq), not equal (ne), greater (gt), less (lt).
|
||||
.TP
|
||||
QS_SetEnvIfQuery <regex> [!]<variable>[=value], directive works quite similar to the SetEnvIf directive of the Apache module mod_setenvif, but the specified regex is applied against the query string portion of the request line. The directive recognizes the occurrences of $1..$9 within value and replaces them by the sub\-expressions of the defined regex pattern.
|
||||
.TP
|
||||
QS_SetEnvIfParp <regex> [!]<variable>[=value], directive parsing the request payload using the Apache module mod_parp. It matches the request URL query and the HTTP request message body data as well ('application/x\-www\-form\-urlencoded', 'multipart/form\-data', and 'multipart/mixed') and sets the defined process variable (quite similar to the QS_SetEnvIfQuery directive). The directive recognizes the occurrences of $1..$9 within value and replaces them by the sub\-expressions of the defined regex pattern. This directive activates mod_parp for every request to the virtual host. You may deactivate mod_parp for selected requests using the SetEnvIf directive: unset the variable 'parp' to do so. Important: request message body processing requires that the server loads the whole request into its memory (at least twice the length of the message). You should limit the allowed size of the HTTP request message body using the QS_LimitRequestBody directive when using QS_SetEnvIfParp!
|
||||
.TP
|
||||
QS_SetEnvIfBody <regex> [!]<variable>[=value], parses the request body using the Apache module mod_parp. Specify the content types to process using the mod_parp directive PARP_BodyData and ensure that mod_parp is enabled using the SetEnvIf directive of the Apache module mod_setenvif. You should limit the allowed size of HTTP requests message body using the QS_LimitRequestBody directive when using mod_parp. The directive recognizes the occurrence of $1 within the variable value and replaces it by the sub\-expressions of the defined regex pattern.

||||
.TP
|
||||
QS_SetEnvStatus (deprecated, use QS_SetEnvIfStatus)
|
||||
.TP
|
||||
QS_SetEnvIfStatus <status code> <variable>, adds the defined request environment variable if the HTTP status code matches the defined value. The value 'QS_SrvMinDataRate' may be used as a special status code to set a QS_Block event in order to handle connection close events caused by QS_SrvMinDataRate rules while the status 'NullConnection' may be used to mark connections which are closed before any HTTP request has ever been received. The 'QS_SrvMaxConnPerIP' value may be used to count QS_Block events for connections closed by the QS_SrvMaxConnPerIP directive. The 'BrokenConnection' value may be used to mark clients not reading the full HTTP response.

.TP
|
||||
QS_SetEnvResBody (deprecated, use QS_SetEnvIfResBody)
|
||||
.TP
|

.TP
|
||||
QS_SetEnvRes <variable> <regex> <variable2>[=<value>], sets the environment variable2 if the regular expression matches against the value of the environment variable. Occurrences of $1..$9 within the value and replace them by parenthesized subexpressions of the regular expression.

.SH NAME
|
||||
qsdt calculates the elapsed time between two related log messages.
|
||||
.SH SYNOPSIS
|
||||
qsdt [\-t <regex>] \-i <regex> \-s <regex> \-e <regex> [\-v] [<path>]
|
||||
.SH DESCRIPTION
|
||||
qsdt is a simple tool to search two different messages in a log file and calculates the elapsed time between these lines. The two log messages need a common identifier such an unique request id (UNIQUE_ID), a thread id, or a transaction code.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
\-t <regex>
|
||||
Defines a pattern (regular expression) matching the log line's timestamp. The pattern must include two sub\-expressions, one matching hours, minutes and seconds the other matching the milliseconds. Default pattern is ([0\-9]{2}:[0\-9]{2}:[0\-9]{2})[.,]([0\-9]{3})
|
||||
.TP
|
||||
\-i <regex>
|
||||
Pattern (regular expression) matching the identifier which the two messages have in common. The sub\-expression defines the part which needs to be extracted from the matching string. Note: You can also use the start (\-s) and end (\-e) pattern to define the sub\-expression matching this identifier.
|
||||
.TP
|
||||
\-s <regex>
|
||||
Defines the pattern (regular expression or literal string) identifying the first (start) of the two messages.
|
||||
.TP
|
||||
\-e <regex>
|
||||
Defines the pattern (regular expression or literal string) identifying the second (end) of the two messages.
|
||||
.TP
|
||||
\-v
|
||||
Verbose mode.
|
||||
.TP
|
||||
<path>
|
||||
Defines the input file to process. qsdt reads from from standard input if this parameter is omitted.
|
||||
.SH EXAMPLE
|
||||
Sample command line arguments:
|
||||
|
||||
\-i ' ([a\-z0\-9]+) [A\-Z]+ ' \-s 'Received Request' \-e 'Received Response'
|
||||
|
||||
matching those sample log messages:
|
||||
2018\-03\-12 16:34:08.653 threadid23 INFO Received Request
|
||||
2018\-03\-13 16:35:09.891 threadid23 DEBUG MessageHandler Received Response
|
||||
|
||||
.SH NOTE
|
||||
The four patterns (t,i,s,e) are concatenated into two search patterns:
|
||||
first (start): [t (HH:MM:SS)(SSS) ].*[i (id) ].*[s ]
|
||||
second (end): [t (HH:MM:SS)(SSS) ].*[i (id) ].*[e ]
|
||||
|
||||
And the three sub\-expression are used to extract the timestamp and the unique identifier that the start and end message have in common. This means that you could specify the sub\-expression for the unique identifier in the start (\-s) or end (\-e) pattern alternatively, e.g. in case the identifier is at the end of the log line.

|
||||
|
||||
.SH NAME
|
||||
qsfilter2 \- an utility to generate mod_qos request line rules out from existing access/audit log data.
|
||||
.SH SYNOPSIS
|
||||
qsfilter2 \-i <path> [\-c <path>] [\-d <num>] [\-h] [\-b <num>] [\-p|\-s|\-m|\-o] [\-l <len>] [\-n] [\-e] [\-u 'uni'] [\-k <prefix>] [\-t] [\-f <path>] [\-v 0|1|2]
|
||||
.SH DESCRIPTION
|
||||
mod_qos implements a request filter which validates each request line. The module supports both, negative and positive security model. The QS_Deny* directives are used to specify request line patterns which are not allowed to access the server (negative security model / deny list). These rules are used to restrict access to certain resources which should not be available to users or to protect the server from malicious patterns. The QS_Permit* rules implement a positive security model (allow list). These directives are used to define allowed request line patterns. Request which do not match any of these patterns are not allowed to access the server.
|
||||
|
||||
qsfilter2 is an audit log analyzer used to generate filter rules (perl compatible regular expressions) which may be used by mod_qos to deny access for suspect requests (QS_PermitUri rules). It parses existing audit log files in order to generate request patterns covering all allowed requests.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
\-i <path>
|
||||
Input file containing request URIs. The URIs for this file have to be extracted from the servers access logs. Each line of the input file contains a request URI consisting of a path and and query.
|
||||
Example:
|
||||
/aaa/index.do
|
||||
/aaa/edit?image=1.jpg
|
||||
/aaa/image/1.jpg
|
||||
/aaa/view?page=1
|
||||
/aaa/edit?document=1
|
||||
|
||||
These access log data must include current request URIs but also request lines from previous rule generation steps. It must also include request lines which cover manually generated rules. You may use the 'qos\-path' and 'qos\-query' variables to create an audit log containing all request data (path and query/body data). Example: 'CustomLog audit_log %{qos\-path}n%{qos\-query}n'. See also http://mod\-qos.sourceforge.net#qsfiltersample about the module settings.
|
||||
.TP
|
||||
\-c <path>
|
||||
mod_qos configuration file defining QS_DenyRequestLine and QS_PermitUri directives. qsfilter2 generates rules from access log data automatically. Manually generated rules (QS_PermitUri) may be provided from this file. Note: each manual rule must be represented by a request URI in the input data (\-i) in order to make sure not to be deleted by the rule optimisation algorithm. QS_Deny* rules from this file are used to filter request lines which should not be used for allow list rule generation.
|
||||
Example:
|
||||
# manually defined allow list rule:
|
||||
QS_PermitUri +view deny "^[/a\-zA\-Z0\-9]+/view\\?(page=[0\-9]+)?$"
|
||||
# filter unwanted request line patterns:
|
||||
QS_DenyRequestLine +printable deny ".*[\\x00\-\\x19].*"
|
||||
|
||||
|
||||
.TP

|
||||
.TP
|
||||
\-h
|
||||
Always use a string representing the handler name in the path even the url does not have a query. See also \-d option.
|
||||
.TP
|
||||
\-b <num>
|
||||
Replaces url pattern by the regular expression when detecting a base64/hex encoded string. Detecting sensibility is defined by a numeric value. You should use values higher than 5 (default) or 0 to disable this function.
|

|
||||
Disables redundant rules elimination.
|
||||
.TP
|
||||
\-e
|
||||
Exit on error.
|
||||
.TP
|
||||
\-u 'uni'
|
||||
Enables additional decoding methods. Use the same settings as you have used for the QS_Decoding directive.
|
||||
.TP
|
||||
\-k <prefix>
|
||||
Prefix used to generate rule identifiers (QSF by default).
|
||||
.TP
|
||||

|
||||
.TP
|
||||
\-v <level>
|
||||
Verbose mode. (0=silent, 1=rule source, 2=detailed). Default is 1. Don't use rules you haven't checked the request data used to generate it! Level 1 is highly recommended (as long as you don't have created the log data using your own web crawler).
|
||||
.SH OUTPUT
|
||||
The output of qsfilter2 is written to stdout. The output contains the generated QS_PermitUri directives but also information about the source which has been used to generate these rules. It is very important to check the validity of each request line which has been used to calculate the QS_PermitUri rules. Each request line which has been used to generate a new rule is shown in the output prefixed by "ADD line <line number>:". These request lines should be stored and reused at any later rule generation (add them to the URI input file). The subsequent line shows the generated rule. At the end of data processing a list of all generated QS_PermitUri rules is shown. These directives may be used withn the configuration file used by mod_qos.

|
||||
.TP
|
||||
\-p
|
||||
Used for post processing when reading the log data from a file (cat/pipe). qslog is started using it's offline mode (extracting the time stamps from the log lines) in order to process existing log files. The option "\-pc" may be used alternatively if you want to gather request information per client (identified by IP address (I) or user tracking id (U) showing how many request each client has performed within the captured period of time). "\-pc" supports the format characters IURSBTtDkMEcm. The option "\-pu" collects statistics on a per URL level (supports format characters RSTtD). "\-puc" is very similar to "\-pu" but cuts the end (handler) of each URL.
|
||||
.TP
|
||||
\-v
|
||||
Verbose mode.
|
||||
.TP
|
||||
\-x [<num>]
|
||||
Rotates the output file once a day (move). You may specify the number of rotated files to keep. Default are 14.
|
||||
.TP
|
||||
\-u <name>
|
||||
Becomes another user, e.g. www\-data.
|
||||

|
||||
\-m
|
||||
Calculates free system memory every minute.
|
||||
.TP
|
||||
\-c <path>
|
||||
Enables the collection of log statistics for different request types. 'path' specifies the necessary rule file. Each rule consists of a rule identifier and a regular expression to identify a request seprarated by a colon, e.g., 01:^(/a)|(/c). The regular expressions are matched against the log data element which has been identified by the 'C' format character.
|
||||
.SH VARIABLES
|
||||
The following environment variables are known to qslog:
|
||||
.TP
|
||||
QSEVENTPATH=<path>
|
||||
Defines a file containing a comma or new line separated list of known event strings expected within the log filed identified by the 'E' format character.
|
||||
.TP
|
||||
QSCOUNTERPATH=<path>
|
||||
Defines a file containing a by new line separated list of rules which reflect possible QS_ClientEventLimitCount directive settings (for simulation purpose / \-pc option). The 'E' format character defines the event string in the log to match (literal string) the 'event1' and 'event2' event names against.
|
||||
|
||||
Rule syntax: <name>:<event1>\-<n>*<event2>/<duration>=<limit>
|
||||
'name' defines the name you have given to the rule entry and is logged along with
|
||||
with the number of times the 'limit' has been reached within the 'duration'.
|
||||
'event1' defines the variable name (if found in 'E') to increment the counter.
|
||||
'event2' defines the variable name (if found in 'E') to decrement the counter (and
|
||||
the parameter 'n' defines by how much).
|
||||
'duration' defines the measure interval (in seconds) used for the
|
||||
QS_ClientEventLimitCount directive.
|
||||
'limit' defines the threshold (number) defined for the QS_ClientEventLimitCount
|
||||
directive.
|
||||
|
||||
Note: If the 'name' parameter is prefixed by 'STATUS', the rule is applied against the HTTP status code 'S' and the 'event1' string shall contain a list of relevant status codes separated by an underscore (while 'event2' is ignored).
|
||||
.SH EXAMPLE
|
||||
Configuration using pipped logging:
|
||||
|
||||

{ "To be, or not to be: that is the question: Whether 'tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And by opposing end them? To die: to sleep; No more; and by a sleep to say we end The heart-ache and the thousand natural shocks That flesh is heir to, 'tis a consummation Devoutly to be wish'd. To die, to sleep; To sleep: perchance to dream: ay, there's the rub; For in that sleep of death what dreams may come When we have shuffled off this mortal coil, Must give us pause: there's the respect That makes calamity of so long life; For who would bear the whips and scorns of time, The oppressor's wrong, the proud man's contumely, The pangs of despised love, the law's delay, The insolence of office and the spurns That patient merit of the unworthy takes, When he himself might his quietus make With a bare bodkin? who would fardels bear, To grunt and sweat under a weary life, But that the dread of something after death, The undiscover'd country from whose bourn No traveller returns, puzzles the will And makes us rather bear those ills we have Than fly to others that we know not of? Thus conscience does make cowards of us all; And thus the native hue of resolution Is sicklied o'er with the pale cast of thought, And enterprises of great pith and moment With this regard their currents turn awry, And lose the name of action.--Soft you now! The fair Ophelia! Nymph, in thy orisonsBe all my sins remember'd.", 0 },
