4# Author: Wim Rijnders, 17-10-2002
5#
6# Description:
7# -----------
8#
9# Nagios host script to check if any specified java processes are running.
10#
11# Implementation Notes:
12# ---------------------
13#
14# check_disk_smb was used as a starting point, since it was written in perl.
15#
16# This script has been created and tested on Linux RH 7.1.
17#
18# I tried OS-X Darwin (BSD), but the ps command works differently.
19# Notably, you can't get a combined list of child processes. The best approach
20# appears to be to use 'ps -wwaxo command' combined with 'ps -M' (or suchlike)

4# Nagios plugin to send notifications using instant messages through a jabber server
5#
6# Note: a) you can send messages to several different IM systems like ICQ,AIM,MSN,etc...
7# b) to test this plugin you can execute it with the arguments needed and write the message followed by a CTRL+D
