Getting Familiar with the Objects Tab

At the beginning and end of a recording session, snapshots are taken of the most common types and classes of object types that occupy the Java heap, that is, the types which instances in total occupy the most memory. The results are shown on the Object tab (Figure 11-1). Abnormal results in the object statistics might help you detect the existence of a memory leak in your application.

The Objects tab

The Objects tab is divided into the following sections:

  1. Start of Recording-this table lists the most common types on the heap at the beginning of the recording.
  2. Filter column-see Filtering Information on how to use this function.
  3. End of Recording-this table lists the most common types on the heap at the end of the recording.
