ActivitiesΒΆ

Yamcs can run background activities whose execution state are tracked in the UI.

Activities Page

Yamcs includes a core set of activity types that cover command execution, stack execution, script execution and manual execution. Yamcs plugins may add more types.

Note

Prior to Yamcs 5.13.0, activities were only available by enabling the Timeline Service. Since then, activities were upgraded to a core Yamcs functionality, and so no longer require presence of the Timeline Service.

Status

An activity can assume one of these statuses:

  • RUNNING: The activity is ongoing

  • CANCELLED: The activity was cancelled

  • SUCCESSFUL: The activity completed successfully

  • FAILED: An error occurred while running the activity

Relation to Timeline

When combining with the Timeline, you can plan activities for future execution:

Planned Activities

Planned activities are submitted via the UI or API to the Timeline (saved as activity items). An activity scheduler monitors all activity items in the Timeline, and submits them to the activity service when due, for immediate execution.
