# Wildard-plugin to monitor "activity" property of Condor nodes.
#
# Author: Šarūnas Burdulis, sarunas(a)mail.saabnet.com, 2008
#
# Runs 'condor_status' and counts virtual machines by their 
# reported Condor "activity" (Idle, Busy, Suspended, Vacating, Benchmarking).  
#
# Parameters understood:
#
#	config   (required)
# 	autoconf (optional - used by munin-config)
#	suggest  (optional - used by munin-config)
#
# Configurable variables:
#
# 	env.condor_status - Path to condor_status executable,
#		defaults to /usr/local/condor/bin/condor_status
# 	env.constraint - Condor ClassAds constraint(s), as they are
#		specified on the condor_status command line. For example, 
#		to monitor 64-bit Linux nodes set:
#		env.constraint 'arch=="x86_64" && opsys=="linux"'
#
# Magic markers - optional - used by installation scripts and
# munin-config:
#
#%# family=contrib
#%# capabilities=autoconf

# optional tag
