How to create a .HAR file

There may be a time when you and/or your team may experience less than ideal platform performance. This should be reported directly to Forecast Support to assist with troubleshooting, gathering information and reporting for in-depth investigation. Part of the troubleshooting process may require you to generate and provide a .HAR file.

A .HAR file is a JSON-formatted archive file format for logging of a web browser's interaction with a site that is primarily used for identifying performance issues such as slow load times and page rendering problems. This file captures browser and platform site details that are essential for determining the cause of the sub-par performance.
