How to setup check_megaraid_sas

1. Make sure you have Megacli installed. In HPC it's installed in /opt/MegaRAID/MegaCli/

2. Download check_megaraid_sas script from Nagios Exchange to the plugins folder of the host. In most systems this is in /usr/lib64/nagios/plugins or /usr/lib/nagios/plugins

3. The MegaCli script has to be run as root, usually nrpe runs as user nrpe. The nagios check script is fully aware of that and uses sudo to call the raid check script. So nrpe needs to be allowed to call this script as root. Use visudo and add this line:

nrpe ALL=(ALL) NOPASSWD: /opt/MegaRAID/MegaCli

OPTION 2 TODO: (check hpc's /etc/sudoers)


4. Add a new command definition to nrpe config : /etc/nagios/nrpe.cfg


5. On the monitoring server, add a service definition as follows:

define service{
	use 			generic-service
	host_name		HPC
	service_description	Check RAID Status
	check_command		check_nrpe_1arg!check_raid

6. Restart Nagios
