+# 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.
