Answer 1

Besides the accepted answer, sometimes performance counters and IIS logs are not enough to track down large and complex monolith applications. In which case, stack information could be helpful. Perfview can help you with this and it's open source.

Say for instance you want to track down .NET stack information and stop whenever a web request takes more than 3 seconds. You would then run the following command at the prompt

perfview collect -StopOnRequestOverMsec:3000 -ThreadTime -NoNGenRundown -Merge:false -Zip:false -LogFile:perfviewlog.log -CircularMB:512 -DataFile:LongRequest.etl

Then use perfview to analyze the LongRequest.etl file and track down the .NET call in question. See more at Microsoft's Channel9.
