PureInsight Alerts periodically searches the captured packets based on filter crite- ria. 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.
