Restart OpenLDAP event handler¶

Presentation¶

The script restart_slapd.sh is an event handler designed for Nagios.

It restart OpenLDAP if the service is CRITICAL in HARD state. OpenLDAP is killed with force if a normal kill takes too much time.

Warning

This script requires root privileges, because it uses the kill command. You have to run Nagios as root or set a SUID bit on the script.

Configuration¶

Edit the script to set these parameters:

SLAPD_PID_FILE: File where OpenLDAP stores its PID

SLAPD_START_CMD: How OpenLDAP is started

TIMEOUT: time to wait before doing a kill -KILL

This plugin, along with all other Nagios plugins from this site, can be downloaded in a single archive.

    command_line    /usr/local/nagios/libexec/eventhandlers/restart_slapd.sh  $SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$
}

Add the event handler to an LDAP check service:

    host_name                somehost
    service_description      LDAP
