Script for checking status of IPVS (IP Virtual Server) nodes through NRPE and reports if both nodes are in MASTER or BACKUP state due to network outages.
Script for checking status of IPVS (IP Virtual Server) nodes through NRPE and reports if both nodes are in MASTER or BACKUP state due to network outages. In this scenario, we have two machines and try to make the most of available resources so we don't use dedicated machine for loadbalancing.

check_ipvs_status.pl should be put on the nodes running ipvsadm. The config line in /etc/nagios/nrpe.conf looks like this:
"command[check_ipvs_status]=/usr/lib64/nagios/plugins/check_ipvs_status.pl -s /usr/bin/sudo -i /sbin/ipvsadm -v virtualnode.example.net"

"virtualnode.example.net" is the the name of the virtual host returned by "ipvsadm -L" command

check_ipvs_mismatch.pl should be put on Nagios server. This script is calling check_ipvs_status.pl through NRPE plugin and read status of the nodes.
