Troubleshooting
Problem
For communication to work properly, the network link speed between a Console and the managed host needs to be greater than 100 Mbps regularly. Where a managed host does not meet bandwidth requirements, the number of a managed host normal system operations are impacted. Replication Download is a mandatory activity for every Managed Host. Replication Download Time (RDT) values recorded in the /var/log/qradar.log file can provide a reliable indication of a possible bandwidth issue before the actual bandwidth test that involves an active data transfer is scheduled.
Symptom
- Backup creation issues
- Deploy issues
- Disk space issues (persistent queue directory size fluctuation)
- Intermittent "Unknown" Managed Host status seen in the GUI
- Event data gaps
