Metrics for Azure NetApp Files

  • Article
  • 3 minutes to read

Azure NetApp Files provides metrics on allocated storage, actual storage usage, volume IOPS, and latency. By analyzing these metrics, you can gain a better understanding on the usage pattern and volume performance of your NetApp accounts.

You can find metrics for a capacity pool or volume by selecting the capacity pool or volume. Then select Metric to view the available metrics:

Usage metrics for capacity pools

  • Pool Allocated Size
    The provisioned size of the pool.

  • Pool Allocated to Volume Size
    The total of volume quota (GiB) in a given capacity pool (that is, the total of the volumes' provisioned sizes in the capacity pool).
    This size is the size you selected during volume creation.

  • Pool Consumed Size
    The total of logical space (GiB) used across volumes in a capacity pool.

  • Total Snapshot Size for the Pool
    The sum of snapshot size from all volumes in the pool.

Usage metrics for volumes

  • Percentage Volume Consumed Size
    The percentage of the volume consumed, including snapshots.
    Aggregation metrics (for example, min, max) are not supported for percentage volume consumed size.
  • Volume Allocated Size
    The provisioned size of a volume
  • Volume Quota Size
    The quota size (GiB) the volume is provisioned with.
  • Volume Consumed Size
    Logical size of the volume (used bytes).
    This size includes logical space used by active file systems and snapshots.
  • Volume Snapshot Size
    The size of all snapshots in a volume.

Performance metrics for volumes

Note

Volume latency for Average Read Latency and Average Write Latency is measured within the storage service and does not include network latency.

  • Average Read Latency
    The average time for reads from the volume in milliseconds.
  • Average Write Latency
    The average time for writes from the volume in milliseconds.
  • Read IOPS
    The number of reads to the volume per second.
  • Write IOPS
    The number of writes to the volume per second.

Volume replication metrics

Note

  • Network transfer size (for example, the Volume replication total transfer metrics) might differ from the source or destination volumes of a cross-region replication. This behavior is a result of efficient replication engine being used to minimize the network transfer cost.
  • Volume replication metrics are currently populated for replication destination volumes and not the source of the replication relationship.

  • Is volume replication status healthy
    The condition of the replication relationship. A healthy state is denoted by 1. An unhealthy state is denoted by 0.

  • Is volume replication transferring
    Whether the status of the volume replication is ‘transferring’.

  • Volume replication lag time
    Lag time is the actual amount of time the replication lags behind the source. It indicates the age of the replicated data in the destination volume relative to the source volume.

Note

When assessing the health status of the volume replication, consider the volume replication lag time. If the lag time is greater than the replication schedule, the replication volume will not catch up to the source. To resolve this issue, adjust the replication speed or the replication schedule.

  • Volume replication last transfer duration
    The amount of time in seconds it took for the last transfer to complete.

  • Volume replication last transfer size
    The total number of bytes transferred as part of the last transfer.

  • Volume replication progress
    The total amount of data transferred for the current transfer operation.

  • Volume replication total transfer
    The cumulative bytes transferred for the relationship.

Throughput metrics for capacity pools

  • Pool allocated throughput
    Sum of the throughput of all the volumes belonging to the pool.

  • Provisioned throughput for the pool
    Provisioned throughput of this pool.

Throughput metrics for volumes

  • Read throughput
    Read throughput in bytes per second.

  • Total throughput
    Sum of all throughput in bytes per second.

  • Write throughput
    Write throughput in bytes per second.

  • Other throughput
    Other throughput (that isn't read or write) in bytes per second.

Volume backup metrics

  • Is Volume Backup Enabled
    Shows whether backup is enabled for the volume. 1 is enabled. 0 is disabled.

  • Is Volume Backup Operation Complete
    Shows whether the last volume backup or restore operation is successfully completed. 1 is successful. 0 is unsuccessful.

  • Is Volume Backup Suspended
    Shows whether the backup policy is suspended for the volume. 1 isn't suspended. 0 is suspended.

  • Volume Backup Bytes
    The total bytes backed up for this volume.

  • Volume Backup Last Transferred Bytes
    The total bytes transferred for the last backup or restore operation.
