Monitoring throughput capacity changes - FSx for Lustre
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Monitoring throughput capacity changes

You can monitor the progress of a throughput capacity modification using the Amazon FSx console, the API, and the Amazon CLI.

Monitoring throughput capacity changes (console)

Open the Amazon FSx console at https://console.amazonaws.cn/fsx/.

  • On the Updates tab in the file system details page, you can view the 10 most recent update actions for each update action type.

    For throughput capacity update actions, you can view the following information.

    Update type

    Supported type is Per unit storage throughput.

    Target value

    The desired value to change the file system's throughput per unit of storage to.

    Status

    The current status of the update. For throughput capacity updates, the possible values are as follows:

    • Pending – Amazon FSx has received the update request, but has not started processing it.

    • In progress – Amazon FSx is processing the update request.

    • Updated; Optimizing – Amazon FSx has updated the file system's network I/O, CPU, and memory resources. The new disk I/O performance level is available for write operations. Your read operations will see disk I/O performance between the previous level and the new level until your file system is no longer in the this state.

    • Completed – The throughput capacity update completed successfully.

    • Failed – The throughput capacity update failed. Choose the question mark (?) to see details on why the throughput update failed.

    Request time

    The time when Amazon FSx received the update request.

Monitoring file system updates (CLI)

  • You can view and monitor file system throughput capacity modification requests using the describe-file-systems CLI command and the DescribeFileSystems API action. The AdministrativeActions array lists the 10 most recent update actions for each administrative action type. When you modify a file system's throughput capacity, a FILE_SYSTEM_UPDATE administrative action is generated.

    The following example shows the response excerpt of a describe-file-systems CLI command. The file system has a target throughput per unit of storage of 500 MB/s/TiB.

"AdministrativeActions": [
    {
        "AdministrativeActionType": "FILE_SYSTEM_UPDATE",
        "RequestTime": 1581694764.757,
        "Status": "PENDING",
        "TargetFileSystemValues": {
          "LustreConfiguration": {
            "PerUnitStorageThroughput": 500
          }
        }
    }
]

    When Amazon FSx processes the action successfully, the status changes to COMPLETED. The new throughput capacity is then available to the file system, and shows in the PerUnitStorageThroughput property.

    If the throughput capacity modification fails, the status changes to FAILED, and the FailureDetails property provides information about the failure.
