debugging eventhandler via nrpe

[Assaf Flatto]

  Hello all

I am trying to implement an event handler on a remote machine , and 
having a problem with the way the status arguments are transferred over 
the NRPE channel .

My config is as such :

define service{
<snip>
  max_check_attempts              3
  event_handler                   
check_nrpe_nonssl!solr-restart!$SERVICESTATE$ $SERVICESTATETYPE$ 
$SERVICEATTEMPT$!-t 200

<snip>
}

On the remote server the nrpe was compiled with --allow-command-args  
,and in  the nrpe.cfg i have the following parameters ?

dont_blame_nrpe=1
debug=1
command_timeout=300
# Event Handler
command[solr-restart]=/usr/local/nagios/libexec/eventhandlers/restart-solr.sh


the event handler script is :
#!/bin/bash
#
# Event handler script for restarting the web server on the local machine
#
# Note: This script will only restart the web server if the service is
# retried 3 times (in a "soft" state) or if the web service somehow
# manages to fall into a "hard" error state.
#

case "$1" in
OK)
  # The service just came back up, so don't do anything...
  ;;
WARNING)
  ;;
UNKNOWN)
  ;;
CRITICAL)
  case "$2" in
  SOFT)

  case "$3" in
  2)
  echo "Too early - not restarting yet"
  exit 0
  ;;
     esac

  case "$3" in
  3)
  echo "Too early - not restarting yet"
  exit 0
  ;;
  esac
  ;;
  HARD)
cd /usr/local/nagios/libexec/eventhandlers/
curl -s -v -u *****:******* --request PUT -d @solr7down.xml http://LB
sleep 5
sudo /etc/init.d/jboss stop

sleep 60
sudo /etc/init.d/jboss start
sleep 15
curl -s -v -u *****:****** --request PUT -d @solr7up.xml http://LB
sleep 3
echo " Event handler restarted the solr service"
  ;;
  esac
  ;;
esac
echo "Event handler restarted the solr service"
exit 0

I can see in the syslog that the script is initiated :
Nov 11 18:15:44 gbc1-solr-07 nrpe[29687]: Host address is in allowed_hosts
Nov 11 18:15:44 gbc1-solr-07 nrpe[29687]: Handling the connection...
Nov 11 18:15:44 gbc1-solr-07 nrpe[29687]: Host is asking for command 
'solr-restart' to be run...
Nov 11 18:15:44 gbc1-solr-07 nrpe[29687]: Running command: 
/usr/local/nagios/libexec/eventhandlers/restart-solr.sh
Nov 11 18:15:44 gbc1-solr-07 nrpe[29687]: Command completed with return 
code 0 and output:

But the event handler is not preforming the tasks it is meant to .


when i initiate the command manually

~/libexec/check_nrpe -H <host> -n -c solr-restart -a " Critical HARD 3" 
-t 200
it is running fine .
I know it is an issue with the transfer of the arguments to the nrpe - 
but i am missing something to make sure they are parsed and sent properly .

Anyone can point me to the sign in front of me i am blindingly missing ?

Thanks
