Clarification on Granularity of DCGM_FI_PROF_NVLINK_RX_BYTES and DCGM_FI_PROF_NVLINK_TX_BYTES Metrics

Ask your question

I would like to clarify the granularity of the following NVLink metrics exposed by DCGM:

DCGM_FI_PROF_NVLINK_RX_BYTES

DCGM_FI_PROF_NVLINK_TX_BYTES

Are these metrics reported per GPU (i.e., aggregated across all NVLink links on the GPU), or are they per NVLink link/channel within a single GPU?
