How to calculate duration of live migration?

SCVMM is obvious way to check it out, but how to do on a host without SCVMM installation?

Thanks,

Eddy

Hi Eddy, you can track event 22507 under Microsoft-Windows-Hyper-V-Worker/Admin for the Live Migration time. See the screenshot for an example.

Basically a Live Migration consists of a Brown-out (copy memory) and Black-out (the final memory transfer and causes a brief pause in service) period. You can track 22508 and 22509 events for these as well

Just wondering why you want to calculate Live Migration duration.

It suposed to be transparent for the user, so if it takes 1 or 5 minutes does it really matter?

My asking is about an inquiry, they like to audit their VM performance in an environment w/o SCVMM. The best thing to them is to find a calculation based on events log, then they could batch it.

Thanks, winfred.

Is there any event indicating when the migration start? If so I could use the delta of two logged time to calculate the migration period?

Thanks,

Eddy

The event 22507 will directly display the exact migration time in the description (you can see the screenshot of my last post)

No Events found!
