Monitoring 

Purpose

This section provides the basic information needed for using the J2EE Engine monitoring infrastructure. The following topics are covered:

·        Monitoring framework – an overview of the features provided by the monitoring infrastructure

·        Instrumenting an application to provide monitoring data – a description of the tasks each application provider has to fulfill in order to use monitoring in its applications, as well as a step-by-step tutorial for instrumenting monitoring in an application

·        Using a Programmatic Interface to Create and Install Monitors Dynamically – provides a possibility to create configuration groups and to install summary nodes, object nodes and all kinds of monitors directly from a programmatic interface

·        Customizing Configuration Groups Using Third-Party Tools – provides methods to customize your configuration groups programmatically.

·        Retrieving Monitoring Data from an External Client via JMX – a procedure for extracting monitoring data from different monitors using JMX

·        Using the Generic Configuration Reporter – provides for easily building configuration monitors which display in the monitoring tree properties obtained from the property files stored in the database.

·        Types of monitors and their usage – a reference guide to all monitors available in J2EE Engine, their purpose, how they are defined in the monitor-configuration.xml file and in the source code, and how are visualized in the Monitoring Service runtime
