Profile a specific application pool in IIS

Hi there,

I have a server which runs many sites, each under their own application pool.  I want to profile one specific site, and I want to capture call stack information as well so I can drill down into the Creation Stack Trace.  I can start IIS under profiling to do what I am after like this:

dotmemory start-iis --trigger-timer=30s -m=20 -c

Which works great, and captures a snapshot every 30 seconds, max 20, and includes call stack information.  However, on the live server, I only want to do this for ONE application pool.  Can anyone tell me if this is possible please. and if so, how?  I know that I can take snapshots of running applications, and I know I can attach to a specific running process in IIS, but that does not give me the ability to drill down into the callstack, which I am after.  Is it possible?

Thanks for your help.
