Java VisualVM presents data for local and remote applications in
a tab specific for that application. When you open an application
in Java VisualVM, each application opens in a new tab in the main
window. You can have multiple application tabs open.
The Overview tab displays the following general information
about the application and the runtime environment.
PID. This is the process ID of the application. The
process ID is also displayed next to the application node in the
Host. This is the location of the system that the
application is running on.
Main class. The class containing the main
Arguments. Displays any options passed to the
application on startup.
JVM. This is the JDK version of the JVM software.
Java Home. This is the location of the JDK
JVM flags. This displays any flags used by the JVM
software when starting the JDK software.
Heap dump on OOME. This displays the status of the Heap
Dump on OOME option. When enabled, a heap dump is taken when the
application encounters an OutOfMemory exception. You can enabled or
disable the option in the application popup menu.

has stored about the application.
