QRadar: How to properly move a Log Source from one Target Collector to another

How To


Summary

Several outbound protocols use a marker file as a bookmark during event collection. It tells each log source where it last left off while processing events from the last poll. This marker file is stored on the “Target Collector” set within the Overview tab of the log source.

If you have to change Target Collectors for a log source that uses one of these protocols, you need to move the marker file to the new Target Collector. This is so you do not end up with duplicate events in your system. Certain protocols might go too far back to list files found on the destination server or API. This causes the log source to appear to be stopped, or even fill up memory in Ingress to the point it could go Out of Memory (OOM).
