w3wp not showing up in the list of remote apps

[sandeep]

I'm trying to profile IIS applications on a remote machine but the system has more than 10 other .NET applications running. When I try to connect to the remote machine from w3wp does not show up in the list of remote applications

When I try to connect to the w3wp.exe application with the process id using Yourkit .NET API, I get the following exception

Code: Select all

Fixed this issue by setting YOURKIT_HOME. I find it funny that this feature is not specified in any of the docs for .NET profiler. Or did I miss it

It was mentioned in the change list for version 11:

We'll add this to the help.

Alternatively, you could use another constructor of YourKit.Profiler.Api.Controller which takes the user home directory as a parameter in addition to the PID. But I would prefer the approach of setting the YOURKIT_HOME because finding the user home of a server user can be a difficult task.
