How to: Collect Windows Counter Data
Windows Counters are system performance counters that can be collected at set intervals during profiling. In the Marks view of the Profiling Tools report, a row is labeled AutoMark for each collection interval. The row contains columns that describe the performance counter values at that interval. To restrict the analysis to a period of time between two particular marks, select the marks, right-click, and then select Filter By Marks.
