Using the Sessions view is painful and doesn't give you a high level view of all your custom errors. You will need to click on each URL and it may or may not be your error. A better approach I have come across with some help from AppD support team is to use the analytics view and I think that will give you what you want here. In the controller go to Analytics Click on searches on the left Add a new search Write your SQL query to target error messages that you are interested in. E.g. SELECT scripterrordata.message, * FROM browser_records WHERE errortype IS NOT NULL AND scripterrordata.message REGEXP 'SOME_ERROR_MESSAGE.*'  Change the time range on top right to be whatever you need (1day, 2days etc) Hope this helps someone as it took a while to get this answer! ...
