Visualizers that open as a result of selecting
metrics from the Monitor menu on the main console
appear as individual, standalone windows. This behavior allows you
to view a number of individual metrics at the same time. You can easily
move the visualizers around on your monitor screen when observing
live application behavior or when reviewing a saved data set from
a monitoring session. For details about specific monitoring visualizers,
see Using Monitoring Displays.
Visualizers that open as a result of selecting
a profile data file open as tabbed panes within a viewer. Presenting
visualizers within a tabbed pane viewer allows you to open one or
more data sets at the same time. The viewer helps
you keep the visualizers for each data set organized as a group within
its own viewer. For details about specific profiling visualizers,
see Using Profile Displays and Using Specialized Garbage Collection Displays.
Viewers are configured to support the type of
data collected and to support specialized analysis. For example, the
profiling viewer appears when you open an eprof or hprof file. It
provides an initial set of visualizer tabs to display summary data
and an important subset of all the available profiling metrics. Other
metrics are opened into the tabbed pane by selecting them from the Metrics or Estimate menus in the viewer.
The garbage collection (GC) viewer is specialized
to provide a detailed view of -Xverbosegc data. All
available metrics for this data are presented in tabs on opening the
data set. No additional metric menus appear in this viewer.
Both standalone visualizers and tabbed viewers
have tool bars and other controls for manipulating the data display.
