Nagios Event Handlers on Windows

Nagios event handlers are WHERE IT’S AT, BABY, YEAH!  There are some services that I can just automagically restart without any problems.  (WSUS, SQL Agent, etc.) This way, instead of notifying me, Nagios can just fix the problem for me and We Need Never Know.

These instructions assume I’m running NSClient++.

The script is

@echo off
net start %1
@exit 0

(This is kept intentionally minimal so it’ll be reusable.)  I’m referring to this in nsclient.ini, under the “; A list of scripts available to run from the CheckExternalScripts module. Syntax is: <command>=<script> <arguments>” header.

restartwsus=scripts\runcmd.bat wsusservice

On the Nagios server, I’ve defined the check in commands.cfg as:

define command{
 command_name restartwsus
 command_line /usr/lib/nagios/plugins/check_nrpe -H '$HOSTADDRESS$' -c restartwsus
}

and in the service definition as:

define service{
        use                     generic-service
        host_name               wsusserver
        service_description     WSUS
        contacts                me
        notification_options    w,c,r
        notification_period     24x7
        notification_interval   0
        check_command           check_nt!SERVICESTATE!-d SHOWALL -l WsusService
        event_handler           restartwsus
        }

It looks like this is copy and paste-able.
