[Nagios-users] Event Handlers

[Gürkan Aslan]

Hi,

I'm trying to define an event handler for nagios. Actually it will work
same as event handler example
(http://nagios.sourceforge.net/docs/3_0/eventhandlers.html#example) but
it doesn't work... i'm trying to create a file in /tmp folder to test,
but nothing in return. event_handler_enabled = 1 in service definition
and nagios.cfg.

with nagios user, i can create a file under /tmp folder
(touch /tmp/foo). Actually i'm trying to restart a service. I defined a
sudo command for nagios like this (in /etc/sudoers file)

nagios LOCAL=NOPASSWD:/etc/init.d/myservice restart

sudo /etc/init.d/myservice restart command is properly running as nagios
user (I'm switching user by: su - nagios).

But i cannot run both of them via an event handler. As i feel that
nagios couldn't trigger the event file...

Any suggestion?

Best regards

Is your event handler script correctly assigned to your service ?=
=20
(event_handler your-event-handler)

Can you give me your command definition for you event handler, someth=
ing=20
like :

define command{
=09command_name=09your-event-handler
=09command_line=09/usr/local/nagios/libexec/eventhandlers/your-event-=
handler $SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$ $ANY_OTHE=
R_VARIABLE_YOU_MAY_NEED$
=09}

Hi Francis,

Thanks for your answer but i solved the problem.

My Mistakes:
* I must use full path in my bash script.
* Event Handler is triggering the event only for the first state
change.

Best regards

define command{
