How to combine NVPW_MetricType,NVPW_RollupOp and NVPW_Submetric?

What’s the restriction of combining?? <<NVIDIA_Nsight_Perf_SDK_2023.3_Getting_Started_Guide_rev20>> haven’t introducing how to combine three Enumerated values.

Hello [450458340],
If I understand correctly, you are trying to combine the metric base name (something like smsp__warps_launched without any suffices) with these 3 attributes to form a metric name. If so, I hope the following information can help you:

  1. If a metric’s type is NVPW_METRIC_TYPE_COUNTER, you can use the following formula: <metric base name>.<RollupOp>(.<Submetric>), where is optional. One example is, gpc__cycles_elapsed.avg.per_second.

  2. If a metric’s type is NVPW_METRIC_TYPE_RATIO, you can use this: <metric base name>.<Submetric>. For example, lts__average_t_sector_hit_rate_realtime.pct.

  3. If a metric’s type is NVPW_METRIC_TYPE_THROUGHPUT, the format is the same as NVPW_METRIC_TYPE_COUNTER but the Submetric field is not optional.

Note: The supported submetrics of different NVPW_METRIC_TYPEs are different, you can query them by NVPW_MetricsEvaluator_GetSupportedSubmetrics and then apply the above formulas.

Let me know if you have more questions!

Thanks.
