There are three sortable columns shown in the table:
Depending on the aggregation level, this column shows different values:
shows the name of the class or the array type.
shows the name of the package.
- Java EE
shows the display name of the Java EE component. If the display name is different from the
actual class name, the class name is displayed in square brackets.
- Instance count
Shows how many instances are currently allocated on the heap. This instance count
is displayed graphically as well.
Shows the total size of all allocated instances. Note that this is the
shallow size which does not include the size of referenced arrays and
instances but only the size of the corresponding pointers. The size is in bytes and includes
only the object data, it does not include internal JVM structures for the class, nor does it
include class data or local variables.
