Investigating Memory Results > Tuning Garbage Collection and Finding Over-allocations > Examining Garbage Collection Data
Two views are useful for finding a problem: the Call Traces view and the Merged Allocation Points view. Both views show the call traces for garbage collected objects, but from different points.
The Call Traces view shows the data in a traditional Call Graph or Call Tree, much like the Call Graph in JProbe Performance, except with object allocation data instead of times. You may find this view more helpful in understanding the overall allocation behavior.
The Merged Allocations Point view shows the data starting from the allocating method. This view shows the merged allocation traces for a set of objects, which may be more helpful in quickly identifying the cause of a problem.
The Merged Allocations Points view works almost the same way with garbage collection traces as it does with use case objects (see Exploring the Merged Allocation Points View), except that all the objects have been garbage collected, so you cannot go to the Instance Detail view.
The Call Traces view works almost the same way with garbage collection traces as it does with use case objects (see Exploring the Call Traces View), except that all the objects have been garbage collected, so you cannot go to the Instance Detail view.
