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. <pre>define service{ host_name somehost service_description HTTP max_check_attempts 4 event_handler restart-process.sh!my_proecess ...other service variables... } </pre> 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! <pre>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 $ARG1$ } </pre> my restart-process.sh <pre>#!/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 </pre> -- Cordially, Shadhin Rahman
