Log in to the supported database console. If an instance has an exceptional diagnosis issue at the current time, a pop-up window will be pushed in real time in the top right corner of the console to notify you. The message contains the instance ID/name, diagnosis item, and start time, allowing you to quickly understand the instance's diagnostic problems.
