Hi @alexrp25 ,
on the IIS process itself, Dynatrace won't show you any distributed traces. They will be shown on the IIS Application Pool processes. If you can't see any traces on those processes, then deep monitoring is not enabled or the process has not yet been restarted.
No, you don't needy any custom process monitoring rule for that. The actual processing happens in the IIS Application Pool, not in IIS. The Application Pools are monitored by default.
Screenshot from the demo environment - you won't have any services (thus any traces) on the IIS process group (1). You should see services on the IIS Application Pool processes (2).
