Nagios Support Forum

Good morning,

I was taking a look to event_handler in Nagios Core and it specifies an event handler as a trigger such as bellow
define service{
host_name somehost
service_description HTTP
max_check_attempts 4
event_handler restart-httpd
...
}
Once the service has been defined with an event handler, we must define that event handler as a command. An example command definition for restart-httpd is shown below. Notice the macros in the command line that I am passing to the event handler script - these are important!

define command{
command_name restart-httpd
command_line /usr/local/nagios/libexec/eventhandlers/restart-httpd $SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$
}
Now, let's actually write the event handler script (this is the /usr/local/nagios/libexec/eventhandlers/restart-httpd script).

SO I UNDERSTAND WHEN THE SERVICE GOES DOWN THE SCRIPT IS TRIGGERED AND THE THE SERVICE IS RESTARTED.

HOW CAN CONFIGURE THIS IN NAGIOSXI

MANY THANKS IN ADVANCE
KIND REGARDS

I recommend following the following linked documentation for detailed instructions on how to set up an event handler in Nagios XI.
INTRODUCTION TO EVENT HANDLERS
It sounds like you have already completed several of the steps outlined in it.

You may just need to navigate to the Admin section of XI using the bar on top > then click Manage Components under System Extensions on the left pane > click the wrench icon to enter the configuration menu > and enter your command there.
