You can use several different types of Java™ Management Extensions (JMX) MBeans to administer and monitor deployments. Each MBean refers to a specific entity, such as a map, eXtreme Scale, server, replication group, or replication group member.
JMX MBean interfaces and WebSphere eXtreme Scale
Each MBean has get methods that represent attribute values. These get methods cannot be called directly from your program. The JMX specification treats attributes differently from operations. You can view attributes with a vendor JMX console, and you can perform operations in your program or with a vendor JMX console.
