run a script based on event??

[Ludo Bosmans]

Geeza,
Yes of course this is possible.

1) On your winserver install the nrpe service as documented in the
README or INSTALL guide and adapt nrpe.cfg as needed.
So in your nrpe.cfg file (on the win server) there should be a config
entry:
command[reboot_server]=c\reboot.bat

2) Make a bat file that contain the shutdown.exe command with the
correct parameters.

3) In your checkcommands.cfg file create a command(this is an example):

# reboot_win_server
define command{
        command_name	reboot_win_server
        command line	$USER1$/reboot_win_server.sh $HOSTNAME$
$HOSTADDRESS$
}

4) In your plugin directory make a small script(reboot_win_server.sh):
This example is just the minimum

#bin/sh
HOST_NAME=$1
IP_ADDRESS=$2
/usr/lib/nagios/plugins/check_nrpe -H $HOST_ADDRESS -t 5 -c
reboot_server

5) Of course there are alternatives, it is possible to define directly
in the checkcommands.cfg the check_nrpe instead of calling a script:

# reboot_win_server
define command{
        command_name	reboot_win_server
        command line	$USER1$/check_nrpe -H $HOSTADDRESS$ -t 5 -c
reboot_server
}

6) To test, at least install the win site, try a manual execution of the
check_nrpe ... reboot 

7) Finally I didn't really test this explanation, so I hope that I
didn't have make mistakes in my explanation.
Kind regards,

Ludo

Ok im a little confussed now...is the following possible via nagios?

Monitor a temp probe in lab (this i know is possible via snmp)...if the
temp 
value goes critical then run check_nrpe (through an event
handler)...which 
will then run a script on the windows machine?

--->>> can check_nrpe be run as an event handler once the temp value is 
critical?

I can shutdown the windows machine fine as i have already got the
commands 
to do that.  I just need a way to call that script/bat flile when the
temp 
value goes critical.
