Filters help you to reduce the depth of call trees. This can be done by skipping successive calls of methods from classes of standard libraries, application servers, etc., 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.
Filters are also used during profiled application runtime to reduce the profiling overhead.
Non-filtered methods are marked with a filled arrow 
.
Filtered methods have an outlined arrow 
:
Select Settings | Edit Filters... in the main menu to configure filters.
While reviewing a snapshot, 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.
