Substitute for Resource Monitor on Hyper-V Server

I have a Hyper-V 2012 R2 server that is showing high disk activity in Task Manager. I don't know what is causing this high activity and would like to use something like Resource Monitor (resmon.exe) to watch the system. Unfortunately Hyper-V server doesn't have this utility. I wonder if anyone has a recommendation for a tool or method they have used to monitor what a Hyper-V server is busy doing, especially as it relates to disk activity.

One way to check is to use Resource Monitor in-guest across all guests to watch what's happening.

Another is to set up Telegraph, InfluxDB, and a Grafana dashboard to soak up all of the telemetry and give you great graphs!

I learned something new today. The disk activity will stay at or near 100% even without a workload (virtual servers OFF). CPU utilization is next to nothing and RAM is around 20% utilized. If I could see the disk utilization by process that might be enough of a clue.
ProcessMonitor or ProcessExplorer fire up okay? I can't remember.

Something else going on there. Is there a rebuild happening on the RAID controller?
