After logging trace for 'CPU Counters' template, we can see two views (Profile and Total PMC Aggregation) from detail area. We got some different data from these two views. For example: Samples: 'Total PMC Aggregation' has more samples than 'Profile' Process: We can see more process from 'Total PMC Aggregation' than 'Profile'. For example, Unknown(0) is shown on 'Total PMC Aggregation' but not on 'Profile'. Other than above, the same counter value between these two views are also different. Can anyone guide us what's the difference and why? Thanks.
