Learn More About Monitoring and Management Improvements in JDK 8

For users of commercial packages Java SE Advanced and Java SE Suite, JDK 8 includes a new version of Java Mission Control (JMC) that introduces a number of improvements to monitoring and profiling the HotSpot VM. JMC is a powerful set of tools for managing a running application and JVM. You can use it to perform extensive analysis based on detailed monitoring and profiling data.

JMC 5.3.0 reintroduces the Diagnostic Commands tab. This tab can be used to remotely execute commands available via the jcmd utility.

Another big improvement is the addition of content types for attributes. This means that each attribute contains metadata about its physical quantity and units, which helps rendering the attribute values on graphs properly with little or no configuration.

In addition, a number of known issues have been fixed, increasing overall stability and performance

To learn more about JMC 5.3.0, see the JMC User's Guide.

Marcus Hirt has presented a screencast titled Introducing Java Mission Control 5.3.0 during the Java 8 Launch Webcast where new JMC features were discussed in more detail.
