In the vCenter server, configure the VM High Disk Latency alarm, as described in the VMware documentation.
If the alarm is configured, the Server Manager generates a corresponding VMHighDiskLatency event for the virtual machine that is experiencing high disk latency.
The VMHighDiskLatency event provides additional information to identify the impacted virtual machines for PhysicalDisk Down, PhysicalDisk Rebuild, ScsiPath Down, InterSwitchLink Down, FibreChannelPort Down root-cause events. “Disk Rebuild use cases” on page 335 provides scenarios that include the VMHighDiskLatency event.
