- *
- * 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.
