The Young generation section is comprised of three separate spaces that occupy the rightmost vertical slice of this panel. This panel is divided up unto three vertical sections, one for each of the of the generations: the Perm (or Permanent) generation, the Old (or Tenured) generation, and the Young generation. The bottom panel provides a graphical view of the spaces that make up the generational garbage collection system. It also includes the arguments passed to the JVM and the values of certain Java properties exported as instrumentation objects.

This section includes the target application's main class name (or jar file if the application was started with the -jar option), and the arguments to the class's main method. It also contains a scrollable text area that lists miscellaneous information about the configuration of the target Java application and JVM. The top panel, labeled Application Information contains a liveness indicator and the elapsed time since the start of the target Java application. The VisualGC window is upper leftmost window and is comprised of two panels. The Survivor Age Histogram window not only available when the Parallel Scagenge collection (-XX:+UseParallelGC or -XX:+AggressiveHeap) is in use. The visualgc tool will open two or three windows: the Visual GC window, the Graph window, and optionally the Survivor Age Histogram window. If omitted, the default interval is 500 milliseconds. See the Virtual Machine Identifier section for more details.Īn integer value indicating the sampling interval. Which allows virtual machine identifiers to vary from a simple integer representing a local virtual machine identifier to a more complex construction specifying a communications protocol, port number, and other implementation specific values. The syntax of the vmid string largely corresponds to the syntax of a URI. The visualgc takes the following options:Ī string that indicates the target JVM. The formatting and semantics of the vmid are described in the vmid option section below.

The target JVM is identified by its virtual machine identifier, or vmid. The visualgc tool attaches to an instrumented HotSpot JVM and collects and graphically displays garbage collection, class loader, and HotSpot compiler performance data.

See interval in the Options section below.
