check_coraid

Project Notes

Monitor changes on status of a Coraid shelf. Runs commands ‘show -l’ and
‘list -l’ and compares output with a previously stored file.

Requirements:

• Coraid Ethernet Console (cec)
• ‘pexpect’ Python module

Before using the plugin for monitoring a Coraid device you must store its
output on a file to compare against. You can do it with the option ‘–create’.
Do it when the Coraid device is in good status.

Example:


# check_coraid.py -i eth2 –shelf 0 –create


This plugin must run ‘cec’ as root and, if there’s a timeout, must be able
to kill it. That means you need something like this on your /etc/sudoers
file.


nagios ALL= NOPASSWD: /usr/local/lib/nagios/plugins/check_coraid.py


This is giving full privileges to the script, so please check that no one
can overwrite the Nagios plugin neither the ‘cec’ binary.

This script is inspired on ‘aoe-chk-coraid.sh’ by William A. Arlofski
(http://www.revpol.com/coraid_scripts).
