jvisualvm
jvisualvm(1) General Commands Manual jvisualvm(1)
NAME
jvisualvm - Java Virtual Machine Monitoring, Troubleshooting, and Profiling Tool
SYNOPSIS
jvisualvm [ options ]
PARAMETERS
Options, if used, should follow immediately after the command name. Options may be in any order. For a discussion of parameters that apply
to a specific option, see OPTIONS below.
DESCRIPTION
Java VisualVM is an intuitive graphical user interface that provides detailed information about Java technology-based applications (Java
applications) while they are running on a given Java Virtual Machine (JVM(*)). The name Java VisualVM comes from the fact that Java Visu-
alVM provides information about the JVM software visually.
Java VisualVM combines several monitoring, troubleshooting, and profiling utilities into a single tool. For example, most of the function-
ality offered by the standalone tools jmap, jinfo, jstat and jstack have been integrated into Java VisualVM. Other functionalities, such as
some of those offered by the JConsole tool, can be added as optional plug-ins.
OPTIONS
The following option is possible when you launch Java VisualVM.
-J<jvm_option>
Pass this <jvm_option> to the JVM software.
USAGE
Java VisualVM is useful to Java application developers to troubleshoot applications and to monitor and improve the applications' perfor-
mance. Java VisualVM can allow developers to generate and analyse heap dumps, track down memory leaks, perform and monitor garbage collec-
tion, and perform lightweight memory and CPU profiling. Plug-ins also exist that expand the functionality of Java VisualVM. For example,
most of the functionality of the JConsole tool is available via the MBeans Tab and JConsole Plug-in Wrapper plug-ins. You can choose from a
catalog of standard Java VisualVM plug-ins by selecting 'Tools' | 'Plugins' in the Java VisualVM menus.
Start Java VisualVM with the following command:
% jvisualvm <options>

(* The terms "Java Virtual Machine" and "JVM" mean a Virtual Machine for the Java platform.)
