The VMware Guest VM trigger for restarts only takes uptime into account. If a VM is intentionally powered off, the uptime never goes above 0 so the trigger will create a false alarm that cannot be resolved. I assume this affects 6.x too.

May I suggest the following?

1. Modify the existing VMware Guest has been restarted trigger to alert when both the uptime is less than 10 minutes AND the powerstate of the VM is PoweredOn

2. Setup a new Warning state trigger when a VM guest transitions from PoweredOn to PoweredOff state.

3. Setup a new Information state trigger when a VM guest transitions from PoweredOff to PoweredOn state.
