Requirements

You need to have a Nagios NRPE server running on the host.

The host need to have the command /usr/bin/cl_status accessible to user nrpe.

Linux HA Server Script

The script will return a Nagios code of:

OK: when the number of registered nodes and active nodes is equal

WARNING: If at least one node is active

CRITICAL: If the cluster status could not be accessed or if no nodes are active

You can get it here: media:check_heartbeat.sh

Copy it to your nagios plugins directory, in my case: /usr/local/nagios/libexec/

# cp check_hearbeat.sh /usr/local/nagios/libexec/check_heartbeat.sh# chmod 755 /usr/local/nagios/libexec/check_heartbeat.sh Configuration

Add the following to /etc/nagios/nrpe_local.cfg

command[check_heartbeat]=/usr/local/nagios/libexec/check_heartbeat.sh

and reload nrpe server:

# /etc/init.d/nagios-nrpe-server reload Nagios Server template.cfg

Add the following template:

# check LVS Heartbeatdefine service{ use generic-service name check-heartbeat service_description Linux HA LVS check_command check_nrpe!check_heartbeat} host file

Add the following service definition:

#check heartbeatdefine service{ use check-heartbeat host_name lvs1, lvs2}Retrieved from "http://wiki.debuntu.org/wiki/Linux_HA_Heartbeat/Monitoring_with_Nagios"Categories: Monitoring | Network | Nagios | Heartbeat
