Generating a HAR file

Edit online

HTTP Archive format (HAR) files are used to gather performance data from a web browser. Attaching a HAR file to an IBM® Support ticket helps expedite its resolution.

In addition to capturing header objects and response calls that are generated by a web page, HAR files also capture the length of time it takes to complete the following actions:
  • Connect to the server.
  • Gather DNS information.
  • Transfer assets from the server to the browser.
  • Request an object.

The following sections describe how to generate a HAR file with the browsers that are supported by Envizi™ Supply Chain Intelligence.
