Cluster HyperV Virtual Machine Summary TurnedOff perfmon counter meaning

-

hi,

on standalone  (non-clusterized) hyperv host , hyperv virtual machine summary turnedoff perfmon counter reflects number of "off virtual machines"; great !!!

but, on 2 nodes cluster, hyperv virtual machine summary turnedoff perfmon counter seems uncorrect  (is equal number of vm independently of status on or off).

does check this behavior ?

thanks.

regards,

j.p.


hi!

this may or may not related hyper-v version running.  " virtual machine summary turnedoff " sounds wmi counter me. first hyper-v featured in windows server 2008 not cluster-aware. when virtual machine resources migrated node, vm still showed in hyper-v manager. in 2008 r2 had improved significally. vm must registered local hyper-v, , when vm moved, vm wasn't entirerly cleared out hyper-v on previous node. viewing nodes in scvmm showed correct status, viewing in local hyper-v manager vm in "off" state. wmi counters show also.

so if you're using server 2008, not able poll correct values virtual machine summary counters, local hyper-v considers vms are still present.
