Creating a HAR file for troubleshooting

HAR (short for HTTP Archive) files record network requests generated by your browser. HAR files can be helpful when troubleshooting issues with Metabase performance.

HAR files can contain sensitive information that you submit during the recording, like passwords and API keys. Before sharing the HAR file with anyone, review the file contents in a text editor.

To create the HAR file, follow the instructions for your web browser:

  1. Open Chrome Developer tools. You can right-click anywhere on the page and select “Inspect”.

  2. In Developer tools, switch to the Network tab. The network log recording should start automatically.

  3. With the Network tab open and recording in progress, repeat the steps to reproduce the issue.

  4. Once you’re finished reproducing the issue, right-click anywhere in the table of network calls and select Save all as HAR with content.

Create a HAR file in Edge

  1. Open Edge Developer tools. You can right-click anywhere on the page and select “Inspect”.
