# Nagios/Icinga check for OpenSRF Diagnostic
#
# Returns OK as long as all configured services are running.
#
# Installation: 
# 
# Copy to your Nagios plugins directory (typically /usr/lib/nagios/plugins) on
# the remote server.  Create the command in npre_local.cfg with sudo.  Example:
# 	
#	command[check_osrf]=sudo /usr/lib/nagios/plugins/check_osrf
#
# Then allow the nagios user to run the command on opensrf's behalf by adding 
# the following line using visudo:
#
# nagios ALL=(root)  NOPASSWD: /usr/lib/nagios/plugins/check_osrf
#
# adjusting for the actual location of your Nagios plugins.
