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:

• Chrome
• Edge
• Firefox
• Safari
