/******************************************************************************
*
* CHECK_GAME.C
*
* Program: GAME plugin for Nagios
* License: GPL
* Copyright (c) 1999 Ian Cass (ian@knowledge.com)
*
* Last Modified: $Date$
*
* Mod History
*
* 25-8-99 Ethan Galstad <nagios@nagios.org>
* Integrated with common plugin code, minor cleanup stuff
*
* 17-8-99 version 1.1b
*
* 17-8-99 make port a separate argument so we can use something like
* check_game q2s!27910 with the probe set up as
* check_game $ARG1$ $HOSTADDRESS$ $ARG2$
*
* 17-8-99 Put in sanity check for ppl who enter the wrong server type
*
* 17-8-99 Release version 1.0b
*
* Command line: CHECK_GAME <server type> <ip_address> [port]
*
* server type = a server type that qstat understands (type qstat & look at the -default line)
* ip_address = either a dotted address or a FQD name
* port = defaults game default port
*
*
* Description:
*
* Needed to explore writing my own probes for nagios. It looked
* pretty simple so I thought I'd write one for monitoring the status
* of game servers. It uses qstat to do the actual monitoring and
* analyses the result. Doing it this way means I can support all the
* servers that qstat does and will do in the future.
*
*
* Dependencies:
*
* This plugin uses the 'qstat' command If you don't
* have the package installed you will need to download it from
* http://www.activesw.com/people/steve/qstat.html or any popular files archive
* before you can use this plugin.
