Using sunburst diagrams for understanding Java memory consumption
This screencast shows how to use the sunburst diagram in the biggest objects view of JProfiler’s heap walker to visualize memory consumption of your Java application.
The sunburst diagrams shows a ring with the biggest objects and multiple reference levels of dominated objects in successive outer rings. See the documentation to read about the dominator analysis and the biggest objects view.
In the screencast, a memory snapshot of the eclipse IDE is analyzed and the class loader and classes groupings of the biggest object view are shown.
