The Coverage Statistics view displays usage statistics for a selected type of object. Coverage statistics are available at the package, class, method and instance level.
This view is made of a table where the first column presents the list of
items.
First node is always a summary of all the collected coverage information. It
gives an overall rate for method coverage of the loaded classes.
Three display modes are available depending on what is shown in the first column:
These modes have an effect on sorting and filtering actions but not on the rates displayed for each level. In Class mode, the second column shows its package. In Method mode, the second column shows its class and the third its package.
The data displayed depends what object is selected. The statistics available for each object are summarized in the table below.
Column heading | Package statistics ![]() |
Class statistics![]() |
Method statistics![]() |
---|---|---|---|
Calls The number of method calls. |
Accumulated by package for the loaded classes | Accumulated by class | Count |
Methods missed The number of methods that have not been exercised. |
Accumulated by package for the loaded classes | Accumulated by class |
missed or empty |
Methods hit The number of methods that have been exercised. |
Accumulated by package for the loaded classes |
Accumulated by class | empty or hit |
% Methods hit The rate between the two numbers above. |
A rate for the loaded classes of each package | A rate by class | empty |
Note: The profiling views are described here using Java. Profiling data from a different application context might change the terms and syntax used in the views. For more information, see Understanding application contexts in profiling views.
The following controls are available in the Coverage Statistics view.

The view provides filtering based on the name of the package, class, or method. You can also filter on time or heap size and on particular attributes of the package, class, method, or object instance.
Click the title of a column to sort it. Click the title of the column again
to sort it in reverse order. The title of the column is prefixed with > if the
column is sorted in ascending order or with < if it is sorted in descending
order.
Columns can be hidden or shown.
Also a Choose Columns pop-up menu item is available to select which
columns should be hidden and visible and their relative order
