The Request History button is located at the top-right of your screen within the toolbar.
Clicking this button displays all running and completed tasks. It shows what operations the user performed, how long they took and whether or not the operation completed. If the operation failed, the Message field will display a reason and response code.
Use the Failed, Running and Completed options to filter the history.
The Max entries field displays how many request data records can be displayed. To change this number, simply update it and click the Refresh button.
Click the Clean button to clear all completed historical requests. Only the requests with a status of Running will be displayed.
