I understand I can run 'perfMonitor start' and it will collect machine wide events in a .etl file (the reason why I want to deal with machine wide events is that there doesn't seem to be a way to 'attach' to a process or start up a service. I want to profile a service). Now I want to convert the .etl file to a human readable output. How do I do that?

Thank you.

PerfMonitor has a number of ways of displaying the data in an ETL file.  

PerfMonitor analyze 

Is a good place to start.
