StatusDetails

A detailed status of the command execution. StatusDetails includes more information than Status because it includes states resulting from error and concurrency control parameters. StatusDetails can show different results than Status. For more information about these statuses, see Understanding command statuses in the Amazon Systems Manager User Guide. StatusDetails can be one of the following values:

  • Pending: The command hasn't been sent to any managed nodes.

  • In Progress: The command has been sent to at least one managed node but hasn't reached a final state on all managed nodes.

  • Success: The command successfully ran on all invocations. This is a terminal state.

  • Delivery Timed Out: The value of MaxErrors or more command invocations shows a status of Delivery Timed Out. This is a terminal state.

  • Execution Timed Out: The value of MaxErrors or more command invocations shows a status of Execution Timed Out. This is a terminal state.

  • Failed: The value of MaxErrors or more command invocations shows a status of Failed. This is a terminal state.

  • Incomplete: The command was attempted on all managed nodes and one or more invocations doesn't have a value of Success but not enough invocations failed for the status to be Failed. This is a terminal state.

  • Cancelled: The command was terminated before it was completed. This is a terminal state.

  • Rate Exceeded: The number of managed nodes targeted by the command exceeded the account limit for pending invocations. The system has canceled the command before running it on any managed node. This is a terminal state.
