event_handler arguments ($ARG1$)

[Anurag Gupta]

No, user arguments can not be passed to Nagios event handlers. Look under
the Event Handler columns on this page.

hope this helps

  Subject: [Nagios-users] event_handler arguments ($ARG1$)


  Regarding Nagios 1.1:

  I've tried a number of things, but it appears that event_handler's can't
use user supplied arguments.  I'm trying to use a generic event_handler
script to switch dynamic DNS entries around (so if something goes terribly
wrong on a website, it switches DNS to point to a "sorry, we're down" web
page hosted elsewhere).

  The only way I can make it work is to make individual event_handlers for
each service... which is really a pain in the butt.

  Do event_handlers not support ARG1, ARG2, etc?

  Here's my event handler itself:

  define command {
          command_name    switch_dns
          command_line    /usr/local/nagios/libexec/eventhandlers/switch_dns
$SERVICESTATE$ $STATETYPE$ $SERVICEATTEMPTS$ $ARG1$ $ARG2$ $ARG3$
  }

  My shell script just takes the hostname ($4), and changes the IP to $5 if
the SERVICESTATE is OK, and to $6 if it's CRITICAL.

  Then the service that points to it:

  define service {
          ; lots of stuff removed for readability
         event_handler
switch_dns!website.com!111.111.111.111!222.222.222.222
  }

  Nagios chokes when I do a verify:

  Checking services...
  Error: Event handler command
'switch_dns!website.com!111.111.111.111!222.222.222.222' specified in
service 'image server' for host 'imgserv' not defined anywhere

  Any ideas, or am I going to have to define individual event_handlers?

  Thanks;
  Justin
