The invocation tree view shows a thread resolved top-down call tree which is downward and upward filtered for the selected filter sets.

The entries in the invocation tree have different meanings which are indicated by the displayed icons: node method above threshold This points to a method whose time usage is above the threshold set in the invocation view settings. There are other methods called from this method which are above the threshold as well. node method below threshold This points to a method whose time usage is below the threshold set in the invocation view settings. However, there are other methods called from this method which are above the threshold so this method must be shown to complete the tree up to the root. leaf method above threshold This points to a method whose time usage is above the threshold set in the invocation view settings. There are no other unfiltered methods called from here on. If this is a top level node, it may inform you about direct calls to other filtered classes which never call a method from an unfiltered class. upward filter bag This points to a section of the invocation tree which traverses methods from filtered classes, such as the AWT dispatch mechanism with java core classes filtered or servlets and Enterprise Java Beans called from a filtered application server framework. Between the shown method and the unfiltered children there may be any number of method invocation that are filtered and thus not shown. Every entry in the invocation tree has textual information attached which - depending on the invocation view settings shows a percentage number which is calculated with respect to either the root of the tree or the calling method. a total time measurement in ms or µs. This is the total time that includes calls into other methods. an inherent time measurement in ms or µs. This is the inherent time that does not include calls into unfiltered methods. an invocation count which shows how often the method has been invoked on this path. a method name which is fully qualified or relative with respect to to the calling method. a line number which is only displayed if line number resolution has been enabled in the profiling settings and if the calling class is unfiltered. Note that the line number shows the line number of the invocation and not of the method itself.

When navigating through the call tree by opening method calls, JProfiler automatically expands methods which only call one other method themselves. To quickly expand larger portions of the invocation tree, select a method and choose Edit->Expand 10 levels from the main window's menu or choose the corresponding menu item from the context menu. If you want to collapse an opened part of the invocation tree, select the topmost method that should remain visible and choose Edit->Collapse all from the main window's menu or the context menu.

You can set change the root of the invocation tree to any method by selecting that method and choosing Edit->Set as root from the main window's menu or by choosing the corresponding menu item from the context menu. Percentages will now be calculated with respect to the new root if the percentage base has been set to "total thread time" in the view settings dialog. To return to the full view of all methods called in the current thread or thread group, select Edit->Show all from the main window's menu or the context menu.

You can stop and restart CPU data acquisition to clear the invocation tree and freeze all views to ensure that the invocation tree remains static.
