# COMMANDS.CFG - SAMPLE COMMAND DEFINITIONS FOR NAGIOS 4.1.1
#
#
# NOTES: This config file provides you with some example command definitions
#        that you can reference in host, service, and contact definitions.
#
#        You don't need to keep commands in a separate file from your other
#        object definitions.  This has been done just to make things easier to
#        understand.
