We currently use Nagios to monitor our OpenLDAP server.
Default Nagios plugins:
- Disk usage
- LDAP queries (via anonymous query)
- Load average (5,10,and 15 minute
- Swap usage
Custom scripts run on the local machine via a remote Nagios call:
- Size of Berekeley DB (via db_stat -m)
- Size of slurpd replog
- Size of slapd's memory footprint
- Size of slurpd's memory footprint
- Creation of reject files by slurpd
- Verification that slurpd is running
- Total memory usage
In addition, we also gather statistics on how OpenLDAP is operating via the use of Cricket:
OpenLDAP statistics in Cricket
Here is the ldapmon script we use, which is called via the Cricket Defaults file. It was graciously provided by Andrew Tristan from UC Riverside, and then updated here to include support for the OpenLDAP 2.2 or later releases.
