As I run my own Email server... I take the UPS-emails generated from the APC 
daughtercard when power goes to battery-state and execute a simple DOS
batchfile which just creates a dummy file in an SMB share.

All of the VM's check every 15 minutes to half-hour for the presence of that 
dummy file. If it exists, they shutdown. Call it a simple "heartbeat" event.

That checking also goes along with an automated disk-space check via a crude 
commandline utility I wrote. If space falls below a certain threshold, a dummy
file is created. If the batchfile sees that dummy, I'm sent an email alert.

Same with any processes that suddenly may stop running... ie. BinkD on the 
BBS etc. I wrote a simple program that checks for any running process I 
specify. If it doesn't exist, another dummy tells the batchfile to send email
alerts.

No powershell, WMI, 3rdparty stuff, SNMP or other nonsense in any of this. 
Just simple DOS commands... thus the CPU/resources are never spiked.
