Obtains the console output of an instance. The returned command line output is encoded in Base64 format.

Description

ECS instances are virtualized cloud-based services that cannot be connected to display devices or make mobile snapshots. However, the instance console output for the last start, restart, or shutdown of the instance is cached. You can call the GetInstanceConsoleOutput to monitor and analyze the instance exceptions.

Currently, the phased-out instance types cannot obtain the console output.

Moreover, Windows instances cannot obtain console output as well.
