You can find the tabular data (e.g. properties values) by double clicking the
bold attribute value.
A mbean that uses both constructor parameters and properties can be found as
test.management.BuilderFactoryTarget

Now the complete service interface is available via jmx.
(There are some datatype constraints and the servicemodel should be primitive
or singleton)

+Have a look at the Calculator MBean (test\management\service\Calculator). You

Double click on the 'sum' attribute to get a graph of the sum over time.

== Performance interceptor ==
+The interceptor PerformanceMonitor collects statistical data about calls to
the intercepted service.
+The results are sent to a newly created mbean. For each service method it
displays: number of calls,
+maximum, minimum, average and last execution duration.
+
+The mbean (test\management\service\Calculator\PerformanceMonitor) displays
these values for the Calculator service.
+So just execute some calculations and watch the statistical data changing.
+Double clicking the attribute values displays a graph.

== Monitor ==
+
+Though creation of jmx monitors is not automated it is quite easy by defining
a service point.
+Such a monitor can watch the attribute of another mbean (for example the
average execution time of a service method) and
+send notifications, if a treshold is crossed.

+The implementation uses JMX 1.2 and supports JSR 160 for remote management

+It is depending on MX4J but is working fine with Sun RI too.
+The dependency could be broken up, but there is no standardized way for
creating an HTMLAdapter.
