OpenLDAP
OpenLDAP
Plugin: python.d.plugin Module: openldap
Overview
This collector monitors OpenLDAP metrics about connections, operations, referrals and more.
Statistics are taken from the monitoring interface of a openLDAP (slapd) server
This collector is supported on all platforms.
This collector only supports collecting metrics from a single instance of this integration.
Default Behavior
Auto-Detection
This collector doesn’t work until all the prerequisites are checked.
Limits
The default configuration for this integration does not impose any limits on data collection.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
Configure the openLDAP server to expose metrics to monitor it.
Follow instructions from https://www.openldap.org/doc/admin24/monitoringslapd.html to activate monitoring interface.
Install python-ldap module
Install python ldap module
- From pip package manager
pip install ldap
- With apt package manager (in most deb based distros)
apt-get install python-ldap
- With yum package manager (in most rpm based distros)
yum install python-ldap
Insert credentials for Netdata to access openLDAP server
Use the ldappasswd utility to set a password for the username you will use.
Configuration
File
The configuration file name for this integration is python.d/openldap.conf.
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config python.d/openldap.conf
Options
There are 2 sections:
- Global variables
- One or more JOBS that can define multiple different instances to monitor.
The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
Every configuration JOB starts with a job_name value which will appear in the dashboard, unless a name parameter is specified.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Sets the default data collection frequency. | 5 | False |
| priority | Controls the order of charts at the netdata dashboard. | 60000 | False |
| autodetection_retry | Sets the job re-check interval in seconds. | 0 | False |
| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | False |
| name | Job name. This value will overwrite the job_name value. JOBS with the same name are mutually exclusive. Only one of them will be allowed running at any time. This allows autodetection to try several alternatives and pick the one that works. |
False | |
| username | The bind user with right to access monitor statistics | True | |
| password | The password for the binded user | True | |
| server | The listening address of the LDAP server. In case of TLS, use the hostname which the certificate is published for. | True | |
| port | The listening port of the LDAP server. Change to 636 port in case of TLS connection. | 389 | True |
| use_tls | Make True if a TLS connection is used over ldaps:// | False | False |
| use_start_tls | Make True if a TLS connection is used over ldap:// | False | False |
| cert_check | False if you want to ignore certificate check | True | True |
| timeout | Seconds to timeout if no connection exist | True |
Examples
Basic
A basic example configuration.
username: "cn=admin"
password: "pass"
server: "localhost"
port: "389"
check_cert: True
timeout: 1
Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per OpenLDAP instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| openldap.total_connections | connections | connections/s |
| openldap.traffic_stats | sent | KiB/s |
| openldap.operations_status | completed, initiated | ops/s |
| openldap.referrals | sent | referrals/s |
| openldap.entries | sent | entries/s |
| openldap.ldap_operations | bind, search, unbind, add, delete, modify, compare | ops/s |
| openldap.waiters | write, read | waiters/s |
Alerts
There are no alerts configured by default for this integration.
Troubleshooting
Debug Mode
To troubleshoot issues with the openldap collector, run the python.d.plugin with the debug option enabled. The output
should give you clues as to why the collector isn’t working.
-
Navigate to the
plugins.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
