- .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
