Hi LucD,
i'm having a similar problem which following this discussion, i still do not get it to work.
when i run get-stattype for VM's ,I get the list of available metrics, but without "mem.active.average".
I have raised statistics level to 2 and still No 'mem.active..' metric.
i can get this for a specific VM using VC performance charts but it is not very usefull.
please advise.
Thanks, Avi
