Source lifecycle event tracing. Tracks the lifecycle of source events, such as deploy, undeploy, start, and stop. The dashboard displays the results of the lifecycle of the source events.

Source aggregate event tracing. Provides the following statistics for every execution cycle of the source:

The property aggregates the statistics and provides it periodically at the end of the interval, based on the

sc.source.aggregate.tracing.interval.period

you specify. By default, the interval is set to 60 seconds.

Source controller high availability. Enables message stability acknowledgements in the UM. The source controller uses these to maintain and persist the state of source's execution. If there is a failover or reassignment, the saved state is used to recover the source to its previous running state.

This flag is enabled, by default, for a topology. If you set it to false, the source does not receive the stability acknowledgements and the source controller does not save the running state. For pull-based scheduled sources, if you disable the flags, the state is persisted at the end of the schedule.

Source event tracing. Activity manager records every event that the source generates.
