PureInsight Alerts periodically searches the captured packets based on filter criteria. When it finds packets that match, it populates the alerts graph and also an alert entry in the alerts column where you can download a PCAP file that contains the matching packets. Alerts are useful if you want PureInsight to keep searching for unusual packets or to see trends over a longer period of time.
Multiple alert conditions can be set by the user. Traffic is monitored in semi-real-time to trigger alerts.
When an alert condition is satisfied, the matching portion of traffic is extracted as a PCAP file, and detailed analysis can be performed quickly.
