+# Veritas Cluster System monitor for Nagios.
+# Written by Aaron Bostick (abostick@mydoconline.com)
+# Last modified: 05-22-2002
+#
+# Usage: check_vcs {-g <vcs_group> | -r <vcs_resource> } -s <vcs_system> [-n]
+#
+# Description:
+#
+# This plugin is just a perl wrapper to the vcs commands hagrp and hares. 
+# You specify what group/resource and system you want the status for, and
+# the plugin returns a status code based on the output of either hagrp or 
+# hares.
+#
+# Normal hagrp/hares status codes are ONLINE and OFFLINE depending on where the 
+# cluster service currently lives.  I have added an option, -n, which makes
+# the expected state to be OFFLINE rather than ONLINE so you can run the 
+# plugin on both sides of the cluster and will receive critical alerts when
+# the cluster fails over i.e.  a proper failover will make the standby node
+# go from OFFLINE to ONLINE for the group, so an ONLINE status should alert
+# you! (You do want to know when the cluster fails over, right? :))
+#
+# Output:
+#
+# This plugin returns OK when hagrp/hares -state <grp> -sys <system> returns 
+# ONLINE (or OFFLINE if -n is specified).  Any other hagrp/hares string returns 
+# CRITICAL...  Would a WARNING ever be justified???  UNKNOWN is returned if 
+# hagrp/hares cannot run for some reason.
+# 
+# Examples:
+#
+# Make sure group oracle is ONLINE on server dbserver1:
+#   check_vcs -g oracle -s dbserver1
+#
+# Make sure group oracle is OFFLINE on server dbserver2:
+#   check_vcs -g oracle -s dbserver2 -n
+#
+# Make sure resource oraip is ONLINE on server dbserver1:
+#   check_vcs -r oraip -s dbserver1
+#
+# Make sure resource oraip is OFFLINE on server dbserver2:
+#   check_vcs -r oraip -s dbserver2 -n
+#
