I am glad to hear that Telerik is investigating in improving the managability of Sitefinity through custom instrumentation. However i do not think you understood my original question.
The enterprise library has counters OUT of the box for many of it's application blocks including caching. These are easy to enable when using the microsoft distribution of the enterprise linbrary.
Since these counters are already built in to the application blocks, it should not require any additional coding to enable them, just the right configuration.
Can you at least tell me what version of the enterprise library is included with Sitefinity 4.2 SP1?
I can see it is compiled in to the telerik.sitefinity.utilities.dll however I do not know what version they included code is based on.
