We moved to an enterprise version (master + probes configuration) build 9400, and started experiencing issues with Hyper-V servers monitoring.

• Some performance monitors can't be added (none of the monitors of HyperV Monitors group can be added; "Free Disk Space in GB/MB/%”, so we can’t monitor free space on a Hyper-V space)
• VM's can't be removed from the monitoring system (they appear after removing in a few minutes. We have some test VM's which we don't want to monitor and spend our license on them)
• It says some strange info about a host performance: disk I/O is about 1-1.5 TB per sec...
• It also lies about RAM usage: RAM usage graph shows that it always goes up and down (15%-95%), though all Hyper-V hosts' VM's are running during that time span.
• another strange reports: Disk Read Latency is 132917 Disk Read Latency (Millisecond), threshold value for this monitor is 50 Disk Read Latency (Millisecond)

132197 millisecond / 1000 = 132.197 seconds / 60 seconds = 2.215 minutes.

2+ minutes of latency…. I’m not sure it’s possible (any system would crash if it had such a latency. Or I understand it in a wrong way.)

Anything we can do to fix it?

Thanks in advance!
