Generating a HAR file for troubleshooting performance - akumina/AkuminaTraining GitHub Wiki

When troubleshooting complex issues, it is sometimes necessary for the Akumina support/product team to obtain additional information about the network requests that are generated in your browser while an issue occurs. There are many variables involved when trying to get to the bottom of a performance issue. It could be a latency of the Sharepoint tenant, there could be an issue with a network connection (firewalls / network route), or it could simply be an issue with the Akumina page lifecycle.

Note: Keep in mind that HAR files contain sensitive data, including content of the pages you downloaded while recording,your cookies, which will allow anyone with the HAR file to impersonate your account
