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

sudo /etc/init.d/$6 restart

sudo /etc/init.d/$6 restart
