NagiosEventHandles

Nagios Event Handlers implementation at IIHE

• Usefull link: http://nagios.sourceforge.net/docs/3_0/eventhandlers.html
• Using nagios event handlers with nrpe
  • http://blog.gnucom.cc/2009/event-handlers-in-nagios-using-nrpe/

An example

• The example described here is to restart the dcap service on maite in case is stops. This is somewhat a complex case since it will trigger the restart of dcap over ssh from a script on egon

• Make sure event handlers are enabled

enable_event_handlers=1

• Add this line in the service config file eg. objects/services.cfg in the check_dccp nagios check

event_handler		        handler_restartdcap

• And define the event handler command

define command{
	command_name	handler_restartdcap
	command_line	/usr/lib64/nagios/plugins/handler_restartdcap $SERVICESTATE$ $SERVICESTATETYPE$ '$SERVICEOUTPUT$'
	}

• This script on egon will be executed when the check_dccp on m0 goes into critical state
• Remark: the quotes around serviceoutput are there so that the whole output is sent to the script. When they are not there the output is truncated after the first space
