How it works
Execution feedback and/or errors
When an activity is being executed by the execution engine an observationlifecycle type is sent to the activity_lifecycle topic. Some events are reported through the property event, among this events:
- Start of a reasoner (start)
- End of a reasoner (end)
- Execution errors (error)
This is a strong mechanism you can use to trace the execution of your activities if, at a given moment, you think they are not function as intended.
Security context
- The reasoners get executed in the access control selected at reasoner's creation time
- Observation access control
- Entities access control
