Let's walk through it

 

One way to do this is to monitor the hearbeat on the VM that is communicated from VM tools to the host.  Note that VM tools must be installed on the guest to properly receive the hearbeat metric.

 

So we want to know if a VM has no heartbeat OR of the VM is powered off.  The query for that is 

 

(vm.heartbeat.latest:0 OR vm.powerstate:poweredOff)

 

Now we want to create an alert for each cluster, so that the alert can be emailed to the right recipient.  Let's walk through setting up the alert for ClusterA.  Now the query becomes

 

(vm.heartbeat.latest:0 OR vm.powerstate:poweredOff) AND vm.cluster.name:ClusterA

 

This will only return the VMs in cluster A that have no hearbeat or are PoweredOff.

Now we have the right query, we can click on "alert" to create an alert

 

 

This will take us to the alert configuration screen.  On the 1st tab, I should check evaluate on performance collection, since both Powerstate and Hearbeat are performance metrics so this alert will get computed every time performance data is collected (every 10 mins by default)

 

The criteria tab is next, and that looks fine since we want this alert to fire if any VMs are returned by our search.

On the notifications tab, you have the option to define the properties that show up when an alert fires - I want the Power State of the VM and the heartbeat value (which is a %) to show up.  You can also see that this tab is where the Email address is defined that you want the alert sent to.
