Generating support bundles (HAR files) for browser issues

A HAR file allows you to log your web browser's interaction with a site, such as the Sysdig Monitor application. When debugging issues related to your use of the Sysdig Monitor interface (and particularly for On-Premises installations) you may be asked to provide a HAR file to Sysdig Support to help isolate the root cause of an issue.

NOTE: HAR files contain sensitive information from your browser session while recording, such as the content of the pages you downloaded, cookies, or other personal details.
