The vRealize Operations Manager collects the metrics you use to monitor the performance of your vSAN disk groups.

Disk I/O metrics for the vSAN disk groups include:

  • Disk I/O|Reads Per Second (IOPS)
  • Disk I/O|Writes Per Second (IOPS
  • Disk I/O|Max Observed Reads Per Second (IOPS)
  • Disk I/O|Max Observed Writes Per Second (IOPS)
  • Disk I/O|Throughput Read (bps)
  • Disk I/O|Throughput Write (bps)
  • Disk I/O|Average Read Latency (ms)
  • Disk I/O|Average Write Latency (ms)
  • Disk I/O|Total Bus Resets
  • Disk I/O|Total Commands Aborted per second

The following Disk I/O metrics are disabled by default:

  • Disk I/O|Read Count
  • Disk I/O|Write Count
  • Disk I/O|Average Device Latency
  • Disk I/O|Average Device Read Latency
  • Disk I/O|Average Device Write Latency
  • Disk I/O|Total Number of Errors

Disk space metrics for vSAN disk groups include:

  • Disk Space|Capacity (bytes)
  • Disk Space|Used (bytes)
  • Disk Space|Usage (%)
