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 Oracle 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.
This chapter explains how to write and run clients in the JavaScript programming language to provide monitoring data about GlassFish Server. The ability to program in the JavaScript language is assumed.
Using JavaScript Clients to monitor GlassFish Server has little impact on the runtime performance of a running server. Therefore, you can monitor GlassFish Server in this way both during development and in production.
