What is cmQosShaperV2HistoryBTD?
This read-only PerfCounter64 counts Bytes Tail Dropped by this QoS shaper as retained in the history bin, the archived counterpart to cmQosShaperV2StatsBTD. It gives an administrator historical evidence of when the shaper's output buffer overflowed, useful for correlating past congestion events with customer complaints. For example, finding a large cmQosShaperV2HistoryBTD value in the bin matching a ticket's timestamp confirms the reported slowdown coincided with tail-drop congestion.
