Execution engine

How it works

Execution feedback and/or errors

When an activity is being executed by the execution engine, some events are reported through the activity_lifecycle topic. Among this events:

• Start of a reasoner
• End of a reasoner
• Execution errors

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.

• The reasoners get executed in the access control selected at reasoner's creation time
  • Observation access control
  • Entities access control
