Vizlib Support Investigations - Collecting HAR file with content

Why do I need to send a HAR file?

A HAR file records browser session data, including metadata about the requests themselves. Providing this information helps the Vizlib Support team to better understand and investigate issues you may have. 

We may ask you to reproduce the issue twice in the steps below to ensure that this type of investigation is successful. 

A HAR file is only one type of file that Vizlib Support may request from you as part of the investigation into the root cause of the issue. 

Please note: the screenshots below are for Google Chrome. 


Collecting browser session data of the error

Opening the Developer Tools in a browser

  1. In a new browser session, reproduce the issue. If an error message appears, please take a screenshot as this will also help with our investigation.
  2. Navigate to the top right side of the browser window to view the context menu (three dots) 
  3. Click on the dots to view the options; from the list, click More tools, and from the next menu, click  Developer tools
  4. Pressing F12 or Ctrl+Shift+I displays the Developer tools in other browsers as well.

Viewing the browser requests

The Developer Tools function opens in the same browser (for example, in Chrome by default it displays on the right, and in MS Edge, it displays below).

  1. From the tabs displayed, click on the Network tab to view the browser requests.
  2. The Record button may be grayed out; click it to begin recording (it displays red).
  3. Refresh the browser window to ensure that all the web socket logs are captured as part of the recording.
  4. Reproduce the issue.
  5. The list of requests begins to display.
  6. Right-click on the list of requests, and click Save all as HAR with content.
  7. Save the HAR file locally (e.g. your Desktop). 
  8. Upload the file to the support ticket, or use the option in the Vizlib Portal to share a file with the Vizlib Support team.

Animation shows the steps to create the HAR file as described above.
