Nagios plugin to check current server's RAID status

This plugin checks all RAID volumes (hardware and software) that can be identified.

This is supposed to be a general plugin to run via NRPE. It checks for the various RAID systems, and verifies they are working correctly.

Some checks require root permission, that is acomplished using sudo. Neccessary sudo rules (detected for your system), can be installed when check_raid is invoked with -S argument. You need to be root user and it will add required lines to the sudoers file.

Installing

Download directly from github master (with wget or curl):

wget https://raw.github.com/glensc/nagios-plugin-check_raid/master/check_raid.pl -O check_raid.pl
curl https://raw.github.com/glensc/nagios-plugin-check_raid/master/check_raid.pl > check_raid.pl
chmod +x check_raid.pl

or download in tar format master checkout:

wget https://github.com/glensc/nagios-plugin-check_raid/tarball/master/check_raid.tgz
tar xzf check_raid.tgz
cd glensc-nagios-plugin-check_raid-*

you can grab older releases under tags button

next, setup sudo

./check_raid.pl -S

test run:

./check_raid.pl

for some RAIDs there's need to install extra tools, see Supported RAIDs

Usage

./check_raid.pl [-p|--plugin <name>] [-w|--warnonly]
./check_raid.pl -S
./check_raid.pl -l

Command line arguments

-V  --version           Print check_raid version
-d                      Produce some debug output
-S  --sudoers           Configure /etc/sudoers file
-W  --warnonly          Don't send CRITICAL status
-p  --plugin <name(s)>  Force the use of selected plugins, comma separated
    --noraid=STATE      Set status as STATE if RAID controller is found. Defaults to `UNKNOWN`, but can be: `OK`, `WARNING`, `CRITICAL`, `UNKNOWN`
    --resync=STATE      Set status as STATE if RAID is in resync state. Defaults to `WARNING`, but can be: `OK`, `WARNING`, `CRITICAL`, `UNKNOWN`
-l  --list-plugins      Lists active plugins
