You can call this operation to obtain the command output of an instance. The returned command output is encoded in Base64.

Description

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