Troubleshooting
Problem
A user creates a new log sources and sends the data to QRadar, but the events are not visible in the Log Activity tab. If the user checks in the command line, the tcpdump command shows the packets being received from the source device, but are not displayed in the user interface. This technical note explains how to validate if the interface believes the packets are spoofed or malformed (martian) and how to correct this problem.
Symptom
Events can be seen from the event source by using the tcpdump command, but are not displayed in the Log Activity tab of the user interface.
