# OpenLDAP Input Plugin
|
|
|
|
This plugin gathers metrics from OpenLDAP's cn=Monitor backend.
|
|
|
|
## 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
|
|
# OpenLDAP cn=Monitor plugin
|
|
[[inputs.openldap]]
|
|
host = "localhost"
|
|
port = 389
|
|
|
|
# ldaps, starttls, or no encryption. default is an empty string, disabling all encryption.
|
|
# note that port will likely need to be changed to 636 for ldaps
|
|
# valid options: "" | "starttls" | "ldaps"
|
|
tls = ""
|
|
|
|
# skip peer certificate verification. Default is false.
|
|
insecure_skip_verify = false
|
|
|
|
# Path to PEM-encoded Root certificate to use to verify server certificate
|
|
tls_ca = "/etc/ssl/certs.pem"
|
|
|
|
# dn/password to bind with. If bind_dn is empty, an anonymous bind is performed.
|
|
bind_dn = ""
|
|
bind_password = ""
|
|
|
|
# reverse metric names so they sort more naturally
|
|
# Defaults to false if unset, but is set to true when generating a new config
|
|
reverse_metric_names = true
|
|
```
|
|
|
|
To use this plugin you must enable the [slapd
|
|
monitoring](https://www.openldap.org/devel/admin/monitoringslapd.html) backend.
|
|
|
|
## Metrics
|
|
|
|
All **monitorCounter**, **monitoredInfo**, **monitorOpInitiated**, and
|
|
**monitorOpCompleted** attributes are gathered based on this LDAP query:
|
|
|
|
```sh
|
|
(|(objectClass=monitorCounterObject)(objectClass=monitorOperation)(objectClass=monitoredObject))
|
|
```
|
|
|
|
Metric names are based on their entry DN with the cn=Monitor base removed. If
|
|
`reverse_metric_names` is not set, metrics are based on their DN. If
|
|
`reverse_metric_names` is set to `true`, the names are reversed. This is
|
|
recommended as it allows the names to sort more naturally.
|
|
|
|
Metrics for the **monitorOp*** attributes have **_initiated** and **_completed**
|
|
added to the base name as appropriate.
|
|
|
|
An OpenLDAP 2.4 server will provide these metrics:
|
|

- connections_current

- connections_max_file_descriptors
|
