JProfiler organizes profiling data into view sections which
collect similar or connected views. The view section chooser is located on the
left side of JProfiler's main window, while the single views of a view section
can be selected by choosing the tabs on the bottom of the window. View sections can
also be switched via JProfiler's Views menu or the
keyboard shortcuts which are indicated below.
-
Memory views
(CTRL-1) The memory view section contains views which are concerned with the details of object allocations. -
Heap walker
(CTRL-2) The heap walker view section allows you to take a snapshot of the heap and analyze it in detail. -
CPU views
(CTRL-3) The CPU view section contains views which are concerned with method calls and time measurements. -

Memory views
- Note: It is possible to create and export views from a saved snapshot from the command line or an ant build file. This is especially useful for an automated quality assurance process.
-
The functionality of the various views is strongly dependent on the
state of the current session which is displayed on the right end of the status bar.
-
If the session is
attached,
the complete functionality of all views is available.
-
If the session is
detached,
the functionality of most views is incomplete. Any information which is not
already stored in JProfiler's GUI front end and would have to be queried from the
profiled application is unavailable.
-
If a profiling snapshot is opened,
the status bar displays
Snapshot.
The functionality of all views is identical to the working state
with the exception of the
heap walker view:
The heap walker overview will be shown if a heap snapshot was taken at the
time of saving, otherwise the heap walker will be unavailable.

Most views have specific view settings that can be edited by choosing
View->View settings from the main menu or the corresponding
toolbar button
when the view is active.
