Fiddler Jam

Fiddler Jam is Telerik's new tool designed to facilitate the information exchange between the support and end-user. A simple capture log can provide a lot of useful information to the support team:

  • Video recording and screenshots, along with sharable link
  • Captured user actions such as mouse and keyboard interactions
  • Captured console logs and errors
  • Captured network traffic
  • Captured Local and Session Storage logs

The tool's mission is to reduce the back-and-forth communication in support messages, and save time of our customers. In addition, this would help the support team understand and investigate the issue faster and thus the response time would be shorter.

Install Fiddler Jam

Fiddler Jam provides powerful Chrome extension that could be installed from Chrome Web Store page for Fiddler Jam.

You could find detailed instruction on how to install the extension in Fiddler Jam Extension Installation article.

Capture a Log

Once you have installed the Fiddler Jam browser extension, you can start capturing your use case, or an issue, and then send it to the support team. You can capture issues for both Blazor Server-side applications and Blazor WebAssembly applications.

The detailed capturing instructions can be found in Fiddler Jam extension - Recording a log while below you can find a short video demonstrating the Installation and Capture processes. For convenience, below you can find summarized instructions to follow more easily when capturing a log.

  1. Navigate to about:blank or an empty page to ensure a clean capture
  2. Open the Fiddler Jam extension (the default shortcut is Ctrl+Shift+F)
  3. Configure the recording settings through the Advanced Options button (located above the Start Capture button):
    • Ensure the Mask Post Data switch is disabled if reproducing the issue triggers a postback or a POST request
    • Ensure the Capture video is enabled to provide more details and context in the capture
