The earliest recollection of this bug is traced back to PAN-OS 10.1.0 - July 22, 2025. This bug is fixed in PAN-OS versions 10.1.5. Dedicated Log Collector system and config logs cannot be ingested and are dropped when they are forwarded to a Panorama management server in Management Only mode, resulting in Dedicated Log Collector system and config logs not being viewable on Panorama in Management Only mode. Fixed an issue where, when system logs and configuration logs on a dedicated log detector system were forwarded to a Panorama management server in Management Only mode, the logs were not ingested and were dropped. This caused the dedicated log detector system to not be viewable on a Panorama appliance in Management Only mode.
