You can view performance information for all volumes in the selected cluster from Reporting tab of the NetApp Element Management extension point.

Steps
  1. From the vCenter Plug-in, select NetApp Element Management.

  2. Select Reporting > Volume Performance.

  3. To change how often the data refreshes on the page, click Refresh every list and choose a value.

    The default refresh interval is 10 seconds if the cluster has less than 1000 volumes; otherwise, the default is 60 seconds. If you choose a value of Never, automatic page refreshing is disabled.

Volume performance data

  • Name: Name of the volume when it was created.

  • Account: The name of the account assigned to the volume.

  • Access Groups: The name of the volume access group or groups to which the volume belongs.

  • Volume Utilization %: A percentage value that describes how much the client is using the volume.

    Possible values:

  • 0 = Client is not using the volume

  • 100 = Client is using the max

  • >100 = Client is using the burst

  • Total IOPS: The total number of IOPS (read and write) currently being executed against the volume.

  • Read IOPS: The total number of read IOPS currently being executed against the volume.

  • Write IOPS: The total number of write IOPS currently being executed against the volume.

  • Total Throughput: The total amount of throughput (read and write) currently being executed against the volume.

  • Read Throughput: The total amount of read throughput currently being executed against the volume.

  • Write Throughput: The total amount of write throughput currently being executed against the volume.

  • Total Latency (ms): The average time, in microseconds, to complete read and write operations to a volume.

  • Read Latency (ms): The average time, in microseconds, to complete read operations to the volume in the last 500 milliseconds.

  • Write Latency (ms): The average time, in microseconds, to complete write operations to a volume in the last 500 milliseconds.

  • Queue Depth: The number of outstanding read and write operations to the volume.

  • Average IO Size: Average size in bytes of recent I/O to the volume in the last 500 milliseconds.
