Nagios Support Forum

G'day Support,

Question:
I am attempting to utilize %ENV variables in both a local event handler which appears to work just fine but not so in my global event handler, is that by design or is there some further magic required to get it to function the same?

I am calling the exact same script in both instances but only the local event handler actually sees the NAGIOS_ environmental variables.

In my nagios.cfg
enable_environment_macros=1
enable_event_handlers=1
global_host_event_handler=xi_host_event_handler
global_service_event_handler=xi_service_event_handler

global event handler output

I really would like the global event handler to simply extract the variables from the %ENV hash and not be required to pass arguments into the script...that just adds additional steps when new and exciting things are added.

Please let me know what you think and thanks in advance,
Danny

RESOLVED!

OK I finally figured it out...seems I have to specify the script I am calling via a command I create...so I changed reference from xi_host_event_handler (not sure what/where/how that is) but provided the short name to the command I created which points to my script.

define command {
command_name event_handler_test
command_line $USER1$/test.pl
}

i.e.

# GLOBAL EVENT HANDLERS
#global_host_event_handler=xi_host_event_handler
#global_service_event_handler=xi_service_event_handler
global_host_event_handler=event_handler_test
global_service_event_handler=event_handler_test


Apparently the %ENV is not available from the Host State Change Handler GUI page if you specify the script directly such as

/usr/local/nagios/libexec/test.pl or even the short-name of a defined command event_handler_test

Thanks anyway,
Danny

I am glad your issue has been resolved! I am locking this topic.
