Tracer event types to trace

You can trace the progress of various events that occur in the system by selecting event types to trace in the Tracer Settings dialog box. Examples of rules that produce events are flows, declarative rules, and decision trees rules. You can also trace events related to services and database operations.

For declarative rules, rows of the Tracer output show the operation of the declarative network, that is, the forward and backward chaining computations that occur automatically.
