Let's suppose a user is running a load test and get an error from the controller. What will be your next action?
The first thing to look into when such a situation arises is Log message window in the controller and then the identification of the thrown error. Sometimes VUser script in Vugen needs enhancements, after doing that, run the edited script in debug mode to ensure it doesn’t fail. Refresh the Vuser script in the controller and then again start the scenario.
