The following information can be obtained.

  • id: Storage node ID (uuid)

  • volumeReadIOPS: Number of read operations per second for volumes [IOPS]

  • volumeWriteIOPS: Number of write operations per second for volumes [IOPS]

  • volumeReadTransferRate: Read transfer amount per second for volumes [MiB/sec]

  • volumeWriteTransferRate: Write transfer amount per second for volumes [MiB/sec]

  • driveReadIOPS: Number of read operations per second for drives [IOPS]

  • driveWriteIOPS: Number of write operations per second for drives [IOPS]

  • driveReadTransferRate: Read transfer amount per second for drives [MiB/sec]

  • driveWriteTransferRate: Write transfer amount per second for drives [MiB/sec]

  • cpu: List of CPU performance information of the storage node

  • cpuSummary: CPU performance summary information of the storage node

  • memory: Performance information of the memory

  • Required role: Storage, RemoteCopy, Monitor, or Resource

  1. Verify the ID of the storage node for which you want to obtain performance information.

    REST API: GET /v1/objects/storage-nodes

    CLI: storage_node_list

  2. Obtain performance information.

    Run either of the following commands with the storage node ID specified.

    REST API (low-resolution): GET /v1/objects/performances/storage-nodes/<id>

    REST API (high-resolution): GET /v1/objects/detail-performances/storage-nodes/<id>

    CLI (low-resolution): storage_node_performance_show

    CLI (high-resolution): storage_node_detail_performance_show
