System Metrics

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.
