Filters help you to ignore methods and instances of classes which you are not interested in, such as standard classes, libraries, framework internals, application server core classes etc., so you can more easily focus on own classes of the profiled application.
While reviewing profiling results in a snapshot or in live views, you can use different filters or use none at all. In other words, you do not need to start a new profiling session to start or stop using filters. Views are automatically updated when filter settings are changed.
Filters reduce the depth of call trees and length of stack traces, by skipping successive calls of methods from filtered classes, so you can more easily see the methods of the profiled application.
Filters are applied to views where method call stacks are shown, as well as to hot spot and method list views.
Non-filtered methods are marked with a filled arrow . Filtered methods have an outlined arrow :
Some automatic inspections use filter settings to focus on potential problems in own code of profiled application.
A quick way to turn applying the configured filters on/off is to use the main menu item Settings | Collapse Filtered Calls
Select Settings | Filters... in the main menu to configure filters.
