Creating a .har file

How to create a .har file to troubleshoot difficult to diagnose issues

There are times when gathering data about how your computer is accessing SIMnet may be needed to fix a complex issue. When this happens the Support Team may ask you to create a .har file, which records each request to and from SIMnet. The steps to creating a .har file depend on your browser. Select your browser from the tabs and follow the steps to create a .har file for diagnosis.

Success: You will need to turn on .har file logging prior to experiencing the error you're reporting. If you turn on .har file logging after the error has occurred, the log won't contain the complete data and you will have to resubmit the .har file.
