We use mod_gearman to distribute all of our checks to distributed nodes. We rely on the Global Event Handler component in order to execute a script that generates tickets within our ticketing system when faults occur.

We would like eventhandlers to execute on their respective distributed node. This works; however, when this is enabled the Global Event Handler is also executed on the distributed node. This is not desirable.

My question: is it possible to force Global Event Handlers to execute only on our XI server and not on the distributed mod_gearman nodes?

If you remove the event_handler file from the gearman worker, does that stop it from running?

To clarify, are you saying the Global Event Handlers are firing on BOTH the XI server AND the mod_gearman nodes?

If this is the case, you could modify the xi_host_event_handler & xi_service_event_handler commands to check if it is on the XI server before processing the 2nd 1/2 of the command

The Global Event Handler executes as desired on the XI server. However, if I enable eventhandlers for gearman (i.e. by appending "eventhandler=yes" to the "broker_module" setting within Nagios), the Global Event Handler is executed (or tries to) on the mod_gearman nodes.

I just re-read through the mod_gearman documentation and I do not see any way to prevent global event handlers from being sent to the workers
