  	'''3. Distributed Level: ''' The Distributed services level provides interfaces for implementing JMX managers. As defined by the specification, this level defines management interfaces and components that can operate on agents. Typicall, these services can expose the management view of a JMX agent and its MBeans by mapping their semantic meaning into constructs of data rich protocol e.g. HTML or SNMP.

+ === 5.2 Derby JMX Component Structure ===
  	The basic design principle followed while designing this architecture was to have a MBean, a Model MBean per service instance that is loaded into the monitor. The monitor being a service itself, is managed via System manager MBean.
  
  	The diagram below gives a high level component structure of Derby along with JMX components loaded.

  	Blue components in the diagram services that are started by the monitor. The monitor itself,along with its utility services is represented by red. MBeans, (Model MBeans) are represented by shades of purple and are labeled as "service name" MBean. The arrows represents call backs and returns from JMX Agent to MBean and from MBean to managed resource. The Management service itself is represented in cyan lies at the center of the diagram. A management application is represented in light blue at the top.
