Common log messages new log source and adding it to the traffic analysis engine ] .trafficanalysis.TrafficAnalysisFilter: Now collecting traffic analysis statistics for address.

If an administrator ran tail on /var/log/qradar.log and grep for TrafficAnalysisFilter, they would see QRadar writing events as traffic analysis works on identifying the event source or the final error message when an event source cannot be identified. This section lists the order in which traffic analysis operates.

If a Device or System is not discovered by Traffic Analysis, it is likely that manual log source creation is required followed by a Deploy of the thus created log source.Īppliances that run traffic analysis locally:

The DSM Configuration Guide includes a reference table that outlines which appliances support auto-discovery (Traffic Analysis) to create log sources from Syslog or SNMP events. QRadar supports hundreds of log source types out of the box, with more than 150 DSMs that support automatic log source creation based on traffic analysis in QRadar. Within a few seconds of creation, events are correctly routed through QRadar to the newly created device. After a number of events are successfully identified against a specific device type, the system creates the log source. Traffic analysis is supported on the following protocol types:Įvents received by QRadar are submitted for Auto Detection when device addresses do not yet have a matching configuration. The Traffic Analysis component performs this detection. Each event is tested against suitable DSMs to see whether it can be recognized as an event for that device type. For each device type and ip combination, statistics are kept of successful versus unsuccessful recognition for each unknown event coming through the system.

Traffic Analysis, also known as Auto Detection, allows QRadar to detect and create new Log Sources based on incoming event data.
