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

Metrics for vSAN capacity disk include:

Component

Metrics

Performance

  • Performance|Bus Resets

  • Performance|Commands Aborted Per Second

The following performance metrics are disabled by default:

  • Performance|Device Latency (ms)

  • Performance|Device Read Latency (ms)

  • Performance|Device Write Latency (ms)

  • Performance|Read Requests Per Second

  • Performance|Average Reads Per Second

  • Performance|Write Requests Per Second

  • Performance|Average Writes Per Second

  • Performance|Read Rate

  • Performance|Write Rate

  • Performance|Usage

  • Performance|HDD Errors

SCSI SMART Statistics

Note:

SMART data collection is disabled by default. To enable SMART data collection, ensure that the Enable SMART data collection instance identifier is set to true. For proper data collection, ensure that ESXi hosts in your vCenter Server inventory have CIM service enabled and CIM providers for each SMART metric installed.
