The Solace Events Expert does not actively poll the Solace broker for data. Instead, it passively listens on a configured port and processes any events it receives. Therefore, if you saw a fact named solaceprimary, it means that a Solace broker sent an event which the Events Expert received and processed.
If this fact is no longer visible, it is likely due to fact expiry settings:
Right-click on the Solace_Events service and open Properties.
Navigate to the Fact Options tab.
Check the Expire Facts setting. If it is set to a value greater than 0, facts will expire after the specified time (in milliseconds) if no new data is received for them.
Additionally, since Solace events are also logged, you can check the log files for entries related to solaceprimary. If present, these entries confirm that the event was received and processed. Its disappearance is due to expiry, not an error.
