Event_handler and check_nrpe

[Fulton, David]

I hate to state the obvious, but nrpe usually doesn't have privileges to
start processes. I have a check that I run on remote hosts that requires
root privilege and had to use sudo. I was very restrictive in my sudoers
file to make sure that there were no holes, but it works with no
problems.

	Subject: [Nagios-users] Event_handler and check_nrpe
	
	
	I am trying to use an event_handler to reatrt a process on a
remote server. I use NRPE for this purpose.
	The process works fine when I run the full check_nrpe command
from the command line of the Nagios server:
	 
	#./check_nrpe -H nnn.nn.nnn.nn -c restart_alert_agent_new -a
CRITICAL SOFT 2
	
	However, the restart script on the remote server does not kick
in when the alert is encountered by Nagios itself. Below is the command
defined in misccommands.cfg:
	 
	define command{
	      command_name    restart_alert_agent_new
	      command_line    /usr/local/nagios/libexec/check_nrpe -H
$HOSTADDRESS$ -c restart_alert_agent_new -a $SERVICESTATE$
$SERVICESTATETYPE$ $SERVICEATTEMPT$
	      }
	 
	As mentioned, the restart script in the remote server works fine
when invoked through the command line on Nagios server (above).
	Below is the definition of the service in services.cfg:
	 
	# Service definition
	define service{
	        use                             generic-service ; Name
of service template to use
	 
	        host_name                       CHOCLX-INTTEST
	        service_description             check_total_procs
	        is_volatile                     0
	        check_period                    24x7
	        max_check_attempts              4
	        normal_check_interval           5
	        retry_check_interval            2
	        event_handler_enabled           1
	        event_handler                   restart_alert_agent_new
	        contact_groups
sun-admins,lawson-admins,egate-admins
	        notification_interval           240
	        notification_period             24x7
	        notification_options            u,c
	        notifications_enabled           1
	        check_command
check_nrpe!check_total_procs
	        }
	
	 
	Thank you for your help.
