|Oracle GlassFish Server 3.1 Add-On Component Development Guide|
Monitoring is the process of reviewing the statistics of a system to improve performance or solve problems. By monitoring the state of components and services that are deployed in the GlassFish Server, system administrators can identify performance bottlenecks, predict failures, perform root cause analysis, and ensure that everything is functioning as expected. Monitoring data can also be useful in performance tuning and capacity planning.
An add-on component typically generates statistics that the GlassFish Server can gather at run time. Adding monitoring capabilities enables an add-on component to provide statistics to GlassFish Server in the same way as components that are supplied in GlassFish Server distributions. As a result, system administrators can use the same administrative interfaces to monitor statistics from any installed GlassFish Server component, regardless of the origin of the component.
