CA Application Delivery Analysis automatically runs packet-capture investigations in response to a network or server performance incident. These investigations increase the granularity of performance metric analysis by automatically recording packet-level data that can then be further analyzed.
When a packet capture investigation is performed with the CA Application Delivery Analysis Standard Monitor, the captured data does not always include the traffic of interest. A packet-capture investigation that Multi-Port Monitor performs is far more comprehensive. The short-term packet storage capabilities of the appliance let packet-capture investigations provide details of the traffic at the time the incident occurred.
Options for capture and monitoring let you inspect the packet headers or the entire packet. By default, the appliance stores packet-capture investigation files for 90 days. To access them, log in to the CA Application Delivery Analysis management console and navigate to the Packet Capture Investigations report. Click the Incidents tab to see a link to the Investigations Report page.
When NI GigaStor is assigned to CA Application Delivery Analysis as a monitoring device, it sends the packet digests to CA Application Delivery Analysis for aggregation. CA Application Delivery Analysis packet-capture investigations are based only on the packets that are stored on NI GigaStor.
