How to Capture Network Traffic Logs for Kaltura Support

Last Modified on 04/08/2023 5:47 pm IDT

What is a Web Debugging Tool?

A web debugging tool is a web proxy (HTTP Proxy / HTTP Monitor) that runs on your own computer. Your web browser (or any other Internet application) is configured to access the Internet through the proxy, and this proxy is then able to record and display the network traffic data coming in and out of your computer.

Kaltura recommends using Fiddler for Windows and Charles Proxy for Mac.

When Should You Capture Traffic Logs?

Since traffic logs record communication from and to Kaltura, they can help identify the real cause behind issues that end users see in the front end.
Traffic logs are especially useful for Kaltura Support to investigate issues that are specific to the user’s network or that are not reproducible.
