Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java technology-based applications (Java applications) while they are running on a Java Virtual Machine (JVM).

Java VisualVM organizes JVM data that is retrieved by the Java Development Kit (JDK) tools and presents the information in a way that enables you to quickly view data on multiple Java applications.

You can view data on local applications and applications that are running on remote hosts. You can also capture data about the JVM software and save the data to your local system, and view the data later or share the data with others.

1 Using JVisualVM

To monitor a remote server using JVisualVM you need to setup a SOCKS proxy connection:

Copy

ssh -D 9696 user@remotemachine.com

Then start the local monitor application using that connection. For example, given the server IP address and it's configured JMX port,

Copy

jvisualvm -J-DsocksProxyHost=localhost -J-DsocksProxyPort=9696 \
    --openjmx <REMOTE_SERVER_IP>:<JAVA_JMX_PORT>
