Inspecting Traffic

When the traffic is already captured, you can start analyzing the data.

To extract information about the captured sessions, go to the Live Traffic tab, where each request/response entry (session) is listed in a row with multiple columns fields in the Sessions list. There you can extract valuable data such as the returned status code, the host and the URL, the type of the used protocol (HTTP or HTTPS), the body sizer in bytes, and the HTTP method (GET or POST), and more. The output traffic can be filtered, exported, commented on, and shared for further and detailed inspection.

To open the structured information about the session timings, sizes, requests, and response details in the Overview tab, single-click a session or select multiple sessions.

Live Traffic and session overview

To load the request and response inspectors, double-click a session. The Inspectors tab is a powerful tool that allows you to deep-dive in each session so you and your teammates can debug it or find performance bottlenecks.

The following rules are applied when you are selecting and changing sessions and using the Inspectors tab:

  • Double-click a session to activate the default Inspectors for a selected session. Fiddler Everywhere will automatically decide which inspector is best suited to display the request and response of the chosen session when the inspectors are activated.

  • Single-click a session to activate the last shown Inspectors. This is useful when you want to inspect specific inspectors for many sessions, and you don't need Fiddler Everywhere to load the best inspector based on the requests or response data.

Live Traffic and Inspectors

To save a selected session or multiple selected sessions, use the context menu or use a keyboard shortcut. Saved sessions are available in the Sessions list from which they can be reloaded or shared with collaborators.

The inspection of sessions often happens with teammates or external collaborators. Share a selected session or multiple selected sessions directly from the Live Traffic list or by using the Sessions list.
