QRadar: Events fail to show in the Log Activity tab after pointing an Event Collector to a different Event Processor

Troubleshooting


Problem

You might find that after an Event Collector (EC) connection is modified to point to a different Event Processor (EP), the events from that EC stop showing in the Log Activity tab. 

Symptom

  1. No events are received in the Log Activity tab when a filter to show the events received from the Event Collector is used.
  2. The following message can be seen in the /var/log/qradar.log file of the Event Collector:
