HI!
I was just wondering about this alert I´m getting in scom.
It should not be a performance issue since the vm is alone on a brand new HP-server with a lot of memory. The VM only has one CPU. The server is idle most of the time.
What could be the reason? Is it Numa related? I tried disabling numa on the hyperv-service but no difference. Or is it just a false alert from the veeam hyper-v MP?
"

Hi,
As far as I'm concerned, the issue may be related to "Hyper-V CPU Wait Time Per Dispatch alarm"

Hi!
It does not seem to be the same counter. The alert is from the veeam management pack.
And the value is in percent not ms.
Also the server is a core server so I cant pull up perfmon on it.
Just thought it was strange that a single CPU VM alone on a host was giving the alert.
