see below two separate answers I got from VMware support when bringing this up.
I would prefer to use counters that is supported by VMware.
The customer I am testing it for, primarily wants to be able to see trends on selected vm:s, how it uses vCPU, vMemory, etc. over time, when certain vm:s are running slow and users are complaining.
Maybe it is far to soon to have any suggestions but when I have created a report, it is hard to distinguish which vm goes to which graph-line.
When I point to the graphs, the name of the vm show up, but I would like to be able to point at the vm-name and the graph-line should be BOLD.
Also, when I zoom up the graph, the vm-name does not show up any longer. Only in "normal" zoom this works evidently.
After doing a bit of research it appears as if the perfmon counters were removed from ESX 4 Update 1.
The easiest way to get the counters inside in your virtual machine at this point in time would probably be to use the application provided by Scott Drummond at the following link.http://vpivot.com/2009/09/17/using-perf ... -counters/
Application = http://e-scott.net/share/vmStatsProvide ... elease.exe
This should enable you to see the counters within your virtual machine but as per the disclaimer at the bottom of the page, this is not a feature supported by VMware support."
I'll try answer your questions below:
Also, the app in the link is meant for VI3.
-> It was created for VI3 as there was no option to install the performance counters via VMware tools for VI3.
When the feature was taken out of ESX 4 Update 1, this same application worked successfully for people on vSphere.
So why was it removed?
We're not made aware of why these decisions are made in the technical support department.
The only response that looks to have been returned is that the Perfmon counters from inside the guest were only ever experimentally support anyway.
Is it back again in version 4.1 or will be in the future?
I've checked the tools installation on an ESX 4.1 virtual machine with Windows 2003 installed and there perfmon counters was not available.
As regards future plans, unfortunately again this is something that we would not be aware of in the technical support department.
What I would recommend for this is using the feature request link to get a reply from a product manager.http://www.vmware.com/contact/contactus ... od_request
The form above is directed at product managers and they would be in much better position to let you know what is planned for the future."
