VMware Tools Perfmon Integration

I mentioned in an earlier post that current versions of VMware Tools now include Perfmon Integration. In a Twitter discussion, I found that this tools integration has disappeared from VMware Tools installations of patched hosts.

The VMware Tools installed with the base release of ESXi, 164009, has the Perfmon integration. In the case of ESXi, a few main categories of updates have been released since the main release. Fig. 1. shows the updates since the base release of the product, including the vSphere Update 1 release in Nov. 2009.

In my unscientific experiment, I determined that the VMware Tools update from 175625 release is where the Perfmon integration dropped off. These were the two updates that were selected in the Fig. 1 screen shot of the vSphere Host Update Utility. Subsequent updates that include new versions of VMware Tools will not reinstate the counters, however.

VMware is aware of this situation and they are on the topic, though only through a Twitter conversation. You can drop the Perfmon counters back into the guest operating system if you rerun the vmStatsProvider add-on for Tools. This can be downloaded from the Pivot Point blog post.
