.SH NAME    
jvisualvm \- Visually monitors, troubleshoots, and profiles Java applications\&.
.SH SYNOPSIS    
.sp     
.nf     

\fBjvisualvm\fR [ \fIoptions\fR ]
.fi     
.sp     
.TP     
\fIoptions\fR
The command-line options\&. See Options\&.
.SH 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 specified Java Virtual Machine (JVM)\&. The name Java VisualVM comes from the fact that Java VisualVM provides information about the JVM software visually\&.
.PP
Java VisualVM combines several monitoring, troubleshooting, and profiling utilities into a single tool\&. For example, most of the functionality offered by the standalone tools \f3jmap\fR, \f3jinfo\fR, \f3jstat,\fR and \f3jstack\fR were integrated into Java VisualVM\&. Other functionality, such as some that offered by the \f3jconsole\fR command, can be added as optional plug-ins\&.
.PP
Java VisualVM is useful to Java application developers to troubleshoot applications and to monitor and improve the applications\&' performance\&. Java VisualVM enables developers to generate and analyze heap dumps, track down memory leaks, perform and monitor garbage collection, and perform lightweight memory and CPU profiling\&. You can expand the Java VisualVM functionality with plug-ins\&. For example, most of the functionality of the \f3jconsole\fR command is available through the \fIMBeans\fR Tab and JConsole Plug-in Wrapper plug-ins\&. You can choose from a catalog of standard Java VisualVM plug-ins by selecting \fITools\fR and then \fIPlugins\fR in the Java VisualVM menus\&.
.PP
Start Java VisualVM with the following command:
.sp     
.nf     
\f3%  jvisualvm <options>\fP
.fi     
.nf     
\f3\fP
.fi     
.sp     
.SH OPTIONS    
The following option is available when you launch Java VisualVM
.TP
-J\fIjvm_option\fR
