  • File server metrics measure network throughput utilization, file server CPU and memory, and file server disk throughput and IOPS utilization.

  • Disk I/O metrics measure activity between the file server and the storage volumes.

  • Storage volume metrics measure disk throughput utilization for HDD storage volumes, and IOPS utilization for SSD storage volumes.
