# Apache Input Plugin
|
||||
|
||||
This plugin collects performance information from [Apache HTTP Servers][apache]
|
||||
using the [`mod_status` module][mod_status_module]. Typically, this module is
|
||||
configured to expose a page at the `/server-status?auto` endpoint the server.
|
||||
|
||||
The [ExtendedStatus option][extended_status] must be enabled in order to collect
|
||||
all available fields. For information about configuration of your server check
|
||||
the [module documentation][mod_status_module].
|
||||
|
||||
⭐ Telegraf v1.8.0
|
||||
🏷️ server, web
|
||||
💻 all
|
||||
|
||||
[apache]: https://httpd.apache.org
|
||||
[extended_status]: https://httpd.apache.org/docs/current/mod/core.html#extendedstatus
|
||||
[mod_status_module]: https://httpd.apache.org/docs/current/mod/mod_status.html
|
||||
|
||||
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
||||
|
||||
In addition to the plugin-specific configuration settings, plugins support
|
||||
additional global and plugin configuration settings. These settings are used to
|
||||
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
||||
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
|
||||
|
||||
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
|
||||
|
||||
## Configuration
|
||||
|
||||
```toml @sample.conf
|
||||
# Read Apache status information (mod_status)
|
||||
[[inputs.apache]]
|
||||
## An array of URLs to gather from, must be directed at the machine
|
||||
## readable version of the mod_status page including the auto query string.
|
||||
## Default is "http://localhost/server-status?auto".
|
||||
urls = ["http://localhost/server-status?auto"]
|
||||
|
||||
## Credentials for basic HTTP authentication.
|
||||
# username = "myuser"
|
||||
# password = "mypassword"
|
||||
|
||||
## Maximum time to receive response.
|
||||
# response_timeout = "5s"
|
||||
|
||||
## Optional TLS Config
|
||||
# tls_ca = "/etc/telegraf/ca.pem"
|
||||
# tls_cert = "/etc/telegraf/cert.pem"
|
||||
# tls_key = "/etc/telegraf/key.pem"
|
||||
## Use TLS but skip chain & host verification
|
||||
# insecure_skip_verify = false
|
||||
```

||||
|
||||
