Why is jmx used

This would help you cut down on costs in developing JMX apps. Moreover, it works with many current management solutions. JMX API is open source, making it easier for management system vendors to incorporate the technology into their own solutions.

It can also use lookup and discovery protocols and services, such as Service Location Protocol or the Jini network technology. JConsole is a monitoring tool for Java Management Extensions. It uses a wide array of JMX instrumentation and gives you data on resource consumption as well as the performance of Java applications.

You can use JConsole for monitoring local and remote applications. It is best practice, however, to use JConsole only when you are developing or prototyping applications, rather than using it in production environments. The reason for this is because JConsole uses up a lot of system resources. If you want to connect JConsole to an agent, you would need to specify that agent when you start up. You can also connect to an agent anytime by going to the advanced tab and then type in the URL, username, and password.

JConsole allows you to see a lot of information including the uptime, compile time, live threads , peak, current heap size, current classes loaded, free physical memory and others. For mBeans, you can see all the information on every mBean registered with that server, including a list of all the mBeans arranged by object names.

Switch to the "MBeans" tab. For example, if your Solr include script sets:. When enabled, the following properties are passed to the JVM when starting Solr:. The JMX technology provides a scalable, dynamic management architecture. Every JMX agent service is an independent module that can be plugged into the management agent, depending on the requirements. This component-based approach means that JMX solutions can scale from small-footprint devices to large telecommunications switches and beyond.

The JMX specification provides a set of core agent services.
