GPU STATISTICS GATHERING
GPU statistics can be gathered by pmdanvidia(1) which is a
separate data collection daemon process. It gathers cumulative
utilization counters of every Nvidia GPU in the system, as well
as utilization counters of every process that uses a GPU. When
pcp-atop
notices that the daemon is active, it reads these GPU
utilization counters with every interval.
Find a description about the utilization counters in the section
OUTPUT DESCRIPTION.
