Nagios Plugin - Check Relayd
Comprehensive perl relayd checker.
NOTE:- Requires Perl 5.8 or higher
Nagios user will need sudo access - suggest adding line below to sudoers
_nagios ALL=(ALL) NOPASSWD: /usr/sbin/relayctl show summary
This plugin is designed to run on a local host, if Nagios is not local I suggest you run it via NRPE. However if you are running this on a firewall I would recommend not using NRPE and run a local Nagios useing OCSP/OCHP to pass messages back to your main Nagios.
Check_relayd checks that all redirect & relays loaded by relayd are active. If a redirect/relay or table are down/empty it will give a CRITICAL message with information regarding what has failed. If host(s) are down in a given redirect/relay then it will give a WARNING unless there are 0 up for that relay/redirect in which case it will give a CRITICAL.
If relayd returns any unexpected output (command failure, system errors) this program will return a CRITICAL.
check_relayd [ARGS] -h, -?, --help

-r, --relay, --redirect
Optional -r argument you can give a list of the expected relays/redirect separated by commas (,). If it does not find the relay/redirect return CRITICAL. If a relay/redirect is found that is not defined return WARNING (unless you also use -n see below).
If -n is used do not warn for unexpected relay/redirect found so that we can test just for a single relay/redirect.
If you need any support or help with this plugin or if you find any cool ways of improving it please let me know. Download from Nagios Exchange
