Using the classes perspective

The classes perspective displays the density of class loading over time, which classes were loaded at which time, and whether a class was loaded from the class sharing cache.

The class loading timeline

The class loading graph gives a visual indication of how much class loading occurred in your application over time. Use the graph to identify points in time at which classes were loading at a rate you did not expect.

The classes table

The classes table gives a more detailed view of which classes have been loaded at which times. This table also indicates whether the class was loaded from the shared classes cache.

Column heading Description
Time loaded The time, measured from Java™ Virtual Machine (JVM) start time, when the class was loaded.
Shared cache Whether the class was loaded from the shared classes cache. Not all classes can be cached.
Classname The full name of the loaded class.

Filtering the classes table

Use the text box above the table to filter the output of the classes table. For further information about filtering, see the filtering help topic.

Viewing data for a particular time period

You can select the time interval for displaying data, and making recommendations, by using cropping. For further information about cropping, see Cropping data.
