There was a problem hiding this comment.
Also - m_gcDurationMillis is used in GetLastGCDuration. That reports the duration of just the last GC.
For the accumulating pause counter we need another set of counters. I think we only need to track gen1 and gen2 though.
That would be consistent with not reporting gen0 in GetLastGCDuration.
It should be [m_condemnedGeneration] when accumulating durations - it can be 1 or 2 here.
The reason for m_pauseDurations[1] is that every collection may have multiple pauses - [0] is the blocking phase, [1] is the optional prep for concurrent stage.

I've added support for I will need to re-review the math and check what comes out when API is used - to be sure no millisecond/microsecond mismatches and the like. |
