A quick and dirty Nagios check that does the following:

* Calls /usr/sbin/drbd-overview
* Parses the output collecting stats
* Hardcoded checks for "Connected" and "Primary/Primary" statuses of the haresources defined in /etc/drbd.conf

Installation
------------

* Get this repository
* Copy check_drbd.pl to your path, I use '/usr/local/bin/'
* chmod +x <path_to>/check_drbd.pl
* NOTE: if you want NRPE to run this, you need to add a sudoers statement like such:

root@xxx:~# cat /etc/sudoers 
Defaults        env_reset
nagios ALL=NOPASSWD: /usr/sbin/drbd-overview

* And add the following to your NRPE config:

command[check_drbd]=<path_to>/check_drbd.pl

* Restart NRPE
