System Metrics

Metrics automatically logged by wandb

wandb automatically logs system metrics every 2 seconds, averaged over a 30 second period. The metrics include:

  • CPU Utilization

  • System Memory Utilization

  • Disk I/O Utilization

  • Network traffic (bytes sent and received)

  • GPU Utilization

  • GPU Temperature

  • GPU Time Spent Accessing Memory (as a percentage of the sample time)

  • GPU Memory Allocated

GPU metrics are collected on a per-device basis using nvidia-ml-py3. For more information on how to interpret these metrics and optimize your model's performance, see this helpful blog post from Lambda Labs.
