event handler question with nrpe

[shadih rahman]

can event handler take argument.  I want to have a generic shell script
which take argument as to what process needs to start.  I want to restart
process via nrpe.  Can someone please verfiy if the following will work or
not?  Thanks in advance.

*

define service{
	host_name			somehost
	service_description		HTTP
	max_check_attempts		4
	event_handler			restart-process.sh!my_proecess
	...other service variables...
	}

*

Once the service has been defined with an event handler, we must define that
event handler as a command. Notice the macros in the command line that I am
passing to the event handler - these are important!

define command{
command_name    restart-process.sh
command_line    /usr/lib/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c
restart-process -a $SERVICESTATE$ $STATETYPE$ $SERVICEATTEMPT$
$SERVICEDESC$ 2 $ARG1$
}


my restart-process.sh

#!/bin/sh

maxattempts=$5

case "$1" in
OK)
	# The service just came back up, so don't do anything...
	;;
WARNING)
	# We don't really care about warning states, since the service is
probably still running...
	;;
UNKNOWN)
	# We don't know what might be causing an unknown error, so don't do anything...
	;;
CRITICAL)

	case "$2" in
		

	SOFT)


		case "$3" in
				

		$maxattempts)

			logger -t nrpe-eventhandler "Eventhandler: (Re)starting
/etc/init.d/$4 (state=$1, type=$2, attempt=$3)"

			output=`sudo /etc/init.d/$4 restart`

			`which printf` "%b" "***** Nagios *****\n\nMessage:\tAn init script
was invoked (after $3
attempts).\nDate/Time:\t`date`\n\nHostname:\t`uname
-n`\nService:\t$4\nCommand:\t/etc/init.d/$4
restart\nOutput:\n\n$output" \
			| `which mail` -s "** Eventhandler: Restart of '$4' on host '`uname
-n`'" $notifee
			

			sudo /etc/init.d/$6 restart
			;;
			esac
		;;
				

	HARD)
		# Call the init script to restart the service.
		sudo /etc/init.d/$6 restart
		;;
	esac
	;;
esac
exit 0
