quark server

[Lewis Getschel]

Todd-
It would seem that you (and I) aren't the only ones with license server 
issues <smile>
I'm not familiar with what a 'Quark server' is, but there is the 
check_procs plugin that you can use for checking that there are exactly 
2 processes, or less than 4 processes, etc.

That didn't fit my needs for our flexlm server (I didn't see the 
check_flexlm plugin, so I didn't use that, (next time I'll look first 
before I start coding <grin>)
Here is my plugin that I just wrote last week for a problem that we had.

In my case we found that the lmgrd process wouldn't start (again) 
because a child process was left behind by another process.  The 
criteria that _I_ was given in order to write this was that the child 
process MUST have the license manager process as it's parent (using ps 
id's). NO other combination would be accepted. Hence, I came up with 
this plugin.

Modify as you see fit to fit your needs.

# Script to check the lmgrd daemon for the flexlm license manager process
#
# Written by:   Lewis Getschel
# Date:         4/13/05
# Parameters:   NONE, this checks the local system. Use NRPE to check 
remote systems
# Operation:    Check system for the omega license manager process lmgrd
#               AND make sure that the child process has matching pid#
# Limitiation:  uses nagios recommendation of absolute paths for 
commands, be careful when modifying to keep this in mind!

# Example of expected input from grep command:
#   $ ps -ef | grep lmgrd | grep -v grep
#   root     20648     1  0 15:11 ?        00:00:00
