ASP.NET appDomainResourceMonitoring Counters Returning No Data

Question

I have configured ASP.NET app domain resource monitoring as per this blog post:

http://www.shubho.net/2011/02/performance-monitoring-aspnet.html

Everything seems to be as expected, except that I get no data for the following counters (via perfmon):

\ASP.NET Application(__Total)\% Managed Processor Time (estimated)
\ASP.NET Application(__Total)\% Managed Memory Used (estimated)

\ASP.NET Application(_LM_W3SVC_2_ROOT)\% Managed Processor Time (estimated)
\ASP.NET Application(_LM_W3SVC_2_ROOT)\% Managed Memory Used (estimated)

(They always show 0.0, even though all the other counters in \ASP.NET Application\ work).

Anyone run into this before?

You have to add appDomainResourceMonitoring parameter not only to C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet.config, but to the C:\Windows\Microsoft.NET\Framework64\v4.0.30319 as well. It helped me:
