Disk I/O and Disk Space Metrics for vSAN Disk Groups

The VMware Aria Operations 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 (%)
