It is a case of installing the plugin on your client raid machine and using nagios to call the check_linux_raid with nrpe. I assume you are using nrpe client on your client machines right?
You can also use the mdadm -m (monitor mode) to send you any email alerts when something is up??
I am not really familiar with ninja or merlin, but if they do the same or a similar thing to nrpe, then you wont need nrpe....
Merlin is a database (or something like that) and Ninja is a web interface.
No I dont use nrpe. Not that I know of anyway.
I think I have to use sendmail or postfix to use -m, but I don't want that.
I am currently working on the problem in a different way:
I am working on a script that checks mdadm --detail /dev/md0 if "Failed Devices" is set anything other than "0". The script works when I run it manually, but when I put it in crontab it wont run. My guess would be that it is a problem with permissions.
