In the Packet Analysis panel (Event Analysis > Packet Analysis), you can safely view and interactively analyze the packets and payload of an event that you found in the Navigate view or the Events view.
*You can perform this task in the current view.

Only network events can be analyzed in the Packet Analysis panel. The Packet Analysis panel lists each packet in the event. For each packet, you can see the packet number, the direction (Request or Response), and the packet contents ascii format on the left, hexadecimal format in the middle, and text format on the right. The list of packets is scrollable. When you scroll, the packet or text identification information as well as the Request and Response labels remain visible rather than scrolling out of view.
Each packet is displayed with shading and highlighting to help identify common file patterns: significant header and payload bytes, hexadecimal and ascii bytes, and common file signatures. In addition, you can adjust the request/response display, and display or hide the packet summary.
Below is an example of ther Packet Analysis panel.
|1||Options for exporting a network event. You can export a PCAP, all payloads, request payloads, or response payloads for deeper analysis and to share with others.|
|2||The option to identify common file signatures is activated by default. Common file signatures are highlighted in orange (7); hovering over the highlight reveals the file type.|
|3||The Shade Bytes option adds shading to identify the different hexadecimal bytes (00 to FF) using degrees of highlighting.|
|4||The option to display payloads only hides the packet headers, leaving more space for the payload.|
|5||The Event Header.|
|6||Significant bytes are highlighed in a blue background; as you move the cursor over the highlighting the meta data is displayed in a hover box. For example, Header Meta ip.proto=6 is a tooltip for highlighted meta data in the hexadecimal and binary representation of the packet header.|
|7||Orange highlighting identifies a common file signature. Moving the mouse over the area displays the possible file type in a hover box.|
