Subject: | Run script/command on event |

Can someone point me in the right direction I'd like to be able to shutdown a group of windows servers when an event from a water sensor is triggered,. It is currently monitored and the status change triggers an email. However, I'm hoping to for something like....
Water is detected by sensor
sends trap to Zenoss
Email triggered
------------------------
everything above is currently working
______________
after email is triggered
delay 30 seconds
send command to shutdown 4 severs
I did find http://www.ohjeah.net/2009/03/03/remoe-server-shutdown/ but when my threshold is activated where and how do I enter in this "script"

I suspect you're en-route down a rabbit hole here... You have a shutdown windows from windows, and a shutdown linux from linux script. I'm not even certain I'm going to suggest the correct direction, but I'd look to see if you can build a BASH script that invokes an Active Directory command via SAMBA (samba.org) to shut down a server using ${dev/ManageIp} as the first ARGV of the script.
Once you have a working script you can use a Command Notification to invoke it.

I may actually be headed in the right direction. Further research has lead me to samba's 'net' command. Which is in your example. This means you will have to have Samba installed and joined to AD.
from # man net
RPC SHUTDOWN [-t timeout] [-r] [-f] [-C message]
Shut down the remote server.
-r
Reboot after shutdown.
-f
Force shutting down all applications.
-t timeout
Timeout before system will be shut down. An interactive user of the system can use this time to cancel the shutdown.
-C message
Display the specified message on the screen to announce the shutdown.
so adding a Command Notification containing something along the lines of:
net rpc shutdown -C "WATER SHUTDOWN" -f -S ${dev/ManageIp} -U ${dev/zWinRMUser}%${dev/zWinRMPassword} assuming that the WinRM user used to monitor has rights to shut down.
Note that I am not a Windows Admin and I expressly disclaim any responsibility if this causes windows to fail in some way other than in which windows normally fails.

While I'd like to do a few more real world tests, I've got one working. No need to actually join the AD, just have the samba tools installed. I will add additional lines of the same command for each IP address.
net rpc SHUTDOWN -C "Automated shutdown" -f -I "IPADDRESS HERE" -W DOMAINNAME -U username%password
Now to figure out scripting a linux shutdown (qnap box)

The command is actually a little different for a qnap
http://www.openremote.org/display/docs/Remote+Control+QNAP+Start,+Shutdo...
I'm just confused on this script and can't get it to work. The actual script is supposed to read
#!/bin/bash
username="$1"
hostname="$2"
password="$3"
sshpass -p "$password" ssh "$username"@"$hostname" /sbin/poweroff
and then I call the script ./qnapshutdown.sh username IPAddress SSH-password

I needed to ssh into the qnap so zenoss could add the device to its list of known ssh machines. After that I could get it to shutdown

If you generally trust your environment and don't want to have to ssh in advance to every possible server, check out the -o StrictHostKeyChecking=no option

I used the ssh-keygen util to make the process easier, and it was only the one linux box (raspberry pi runs my WOL cron, and I don't want it waking up my servers in the event of a flood in my server room lol)
