    • Periodic invocation: Before you manually stop a command on periodic invocation, the command process is always in the Running state.
    • One-time execution: The overall invocation state is Running, as long as the command process is in the Running state in any target instance.
  • Finished: The invocation of the command process is completed.
    • Periodic invocation: The command process can never be in the Finished state.
    • One-time execution: When invocations of command processes on all the target instances is completed, the overall invocation state is Finished. Or when you manually stop invocations of the command processes on some target instances and command invocations on other target instances are completed, the overall invocation state is Finished.
  • Failed: The command invocation failed, timed out, or encountered other exceptions.
    • Periodic invocation: The command process can never be in the Failed state.
    • One-time execution: When invocations of the command processes on all the target instances failed, the overall invocation state is Failed.
  • PartialFailed: The invocations of part of command processes failed.
    • Periodical invocation: The command process can never be in the PartialFailed state.
    • One-time execution: The overall invocation state is PartialFailed when any command process is in the Failed state on any target instance.
  • Stopped: The command process is manually stopped.
