HPjmeter 4.3 User's Guide

Sampling minimizes overhead and focuses attention on user code. To discover allocation statistics
about application server classes, use the include and exclude filtering flags in the JVM agent
options.
The reported data is cumulative over the lifetime of the session, and accuracy will improve as the
session length increases.

Current Live Heap Objects
Use this visualizer to obtain an immediate data summary of live objects in the heap each time that
you click the Refresh Live Objects button. This can be especially useful when trying to understand
unexpected behavior in memory usage.
The display shows information for the classes of live objects found. It does not show indirect
references. See Table 22 (page 148).
