Figure 1.1 An environment with many applications that need management.
Each has its own set of configuration and management tools.
model the management interface of each application with an MBean. Next, you
can expose the MBeans for management in a JMX agent, which is available for
any of your existing protocols. Doing so would allow a single point to control all
the applications. From the users' perspective, a single application is presented,
as opposed to a collection of disparate software components. This environment
provides a more uniform and robust solution to the management of the applica-
tion suite. Figure 1.2 illustrates your new environment.
Let's walk through a typical configuration use case for the data storage appli-
cation. Assume a user needs to change the logging level of the application. The
following steps define this use case:
The user opens his favorite management tool and connects to the
JMX agent.
1
The user finds the particular MBean that represents the application and
makes the appropriate log level change.
2
The MBean interacts with the bicycle shop application to configure its
log level.
