Virtual Machines Disk Activity

Virtual Machines Disk Activity report reveals disk I/O performance statistics. This report is helpful for diagnosing read and write latency.

Slow read and write speeds can be indicators of VM memory exhaustion. Use this report together with the VM Memory Utilization report.

• Virtual Machine. Device name/CPU type (CPU index in parenthesis).
• Read: 1 Hour Avg. Average disk read rate.
• Read: 1 Hour Max. Peak disk read rate observed in last hour.
