Nagios script: check_retro_client

2005-07-01 00:00:00

This script was written at the time I was hired by UPC / Liberty Global.

Basic monitor that checks if the Retrospect client is up and running.

This script was quickly hacked together for my current customer, as a Q&D solution for their monitoring needs. It's no beauty, but it works. Written in ksh and tested with:

• Solaris 8
• NRPE 1.9
• Retrospect 7.0
• Should work with other versions as well.

The script sends a Critical if the required process is not running.

UPDATE 19/06/2006:

Cleaned up the script a bit and added some checks that are considered the Right Thing to do. Should have done this -way- earlier!
