What account permissions are needed to do WMI sensors?



I have servers that I want to monitor with WMI sensors (Disk/CPU/Memory/Etc). When I use a Domain Administrator account the sensors work fine. When I specify a local account username the sensors do not work. I looked through a few articles and found that the account has to have local administrator and Distributed DCOM Users access, but it still does not work. I get RPC unavailable errors. I have looked through the 1 article stating multiple reasons for this behavior, and I have done them, and it still does not work unless I use a Domain Administrator account, which I do not want to do.

Dear Terry,

as you already have seen there are dozens of possible tricks and "solutions" you can try for this, sometimes it helps to put the user into the user groups "Performance Log Users" and/or "Performance Monitor Users" but at the end of the day it comes down to the fact, that we don't lay down these permissions for the different performance counters, nor do we know them all by heart. That's two things one would have to ask in Redmond.

best regards.

The steps described in this thread worked for me on PRTG 14 and Windows Server 2012 R2:

Some customers have had success with the list here. Number 3, in particular, is missing from a lot of similar lists: http://infrasightlabs.com/setting-wmi-access-ad-gpo
