    Elastic Compute Service:GetInstanceConsoleOutput

    最終更新日:Nov 25, 2024

    Queries the command output of an Elastic Compute Service (ECS) instance. The returned command output is encoded in Base64.

    Operation description

    • ECS is a virtualized cloud-based service and cannot be connected to display devices. Alibaba Cloud caches system command outputs for the last start, restart, or shutdown of ECS instances. You can call the GetInstanceConsoleOutput operation to query the command outputs.
    • For instances of the retired instance types, you cannot obtain command outputs. For more information, see Retired instance types.
    • You cannot obtain the command outputs of Windows instances.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
