WMI – Resolving System Event Log Full of WMI Performance Adapter Messages

wmi

The System event log continually shows these messages:

The WMI Performance Adapter service
entered the running state.

and then

The WMI Performance Adapter service
entered the stopped state.

Looks like it starts up every 2 minutes, then shuts down about 10 seconds later.

What are these messages from, and is this a normal thing or a sign of something bad happening?

My server is Windows 2008 Server.

Are you using System Center (or some other remote management console that uses WMI) to monitor\manage this system? That's what generally triggers those events in my experience. These are just events, not warnings\errors so there's no specific reason to panic and the rate isn't outrageous.

WMI query of Win32_Product creates events in the W2K8+ Application Event Log

Greg,

I would strongly recommend NOT using Win32_Product if you can avoid it. First, it is really, really slow. Second, and more significant is that you can screw up your system:

The Win32_Product class works by enumerating every MSI package that is installed on the system. When a package is touched, it performs a reconfiguration where the application is validated (and repaired if found to be inconsistent with the original MSI).

This can be a huge problem if you have applications that were configured after install (i.e. previously disabled services can be re-enabled, etc.)

As an alternative, you can do a search on a particular file and check its version to see if an application is installed. Here is a link to a blog post I did describing the technique (and also has a link to an article by Darren Mar-Elia discussing Win32_Product):

To fix the errors on the seconds machine, register the performance counters with Lodctr from a command prompt:

lodctr /T:W3SVC
lodctr /T:InetInfo
lodctr /T:ASP
