Apologies for the delay in posting a reply.....
We have a VMware Tools Monitor in v4.5 of the nworks MP. It detects when the VMware Tools service/processes are not communicating, and it will also detect whether VMtools is an out-of-date version.
Because this monitors more than just the service status in Windows - we are using the VI-API - so it will alert you with a comms failure, even though in Windows it appears the VMtools service is still running.
You'll find this in the Authoring section of SCOM console, in Monitors.
The Monitor name is "nworks VMware: VMware Tools Service Status" and the Target is VMGuest Virtual Machine.
Any queries please let us know!
