How to generate a HAR file in Chrome

Sometimes, when troubleshooting complex issues with Box, it's necessary for us to get some additional information to troubleshoot the issue further. For example, when we receive a report of performance trouble when using Box there are a lot of different factors that may contribute to the problem. To narrow down the cause of the performance problem, we need more data.

Google Chrome, in particular, makes it relatively easy to capture all the data we need using what's called a HAR file. For this reason, we may ask you to generate a HAR file to help troubleshoot the trouble you're experiencing. Please see the following directions for how to generate a HAR file.

How to generate a HAR file

  1. Start by opening Google Chrome. If you don't have Google Chrome and you're free to install additional programs, please download Google Chrome and install it.

  2. In Chrome, go to the page within Box where you are experiencing trouble

  3. Select the Chrome menu at the top-right of your browser window, then select Tools > Developer Tools.

  4. The Developer Tools will open as a panel at the bottom of the page. Click on the Network tab.

  5. Click the record button, a solid black circle, at the top left of the Network tab to begin recording activity in your browser.

  6. Refresh the Box page you're on. The goal is to reproduce the problem you've been experiencing while Google Chrome is recording activity.

  7. Once you've encountered the problem successfully while recording, right-click within the Network tab and click Save as HAR with Content to save a copy of the activity that you recorded.

  8. Within the file window, save the HAR file somewhere convenient.

  9. You're done! Please attach the HAR file to your email or case with us so that we can assist further.
