In this new OTN technical article, RESTful GlassFish Monitoring and Management, Java EE expert Adam Bien shows you how to exploit the built-in monitoring and management capabilities of GlassFish to automate application deployment and gain insight into application performance.
"IT is all about streamlining and automation, so it is somewhat ironic that we developers still tolerate repetitive and boring manual tasks, such as deployment," Bien explains. "Also, our ignorance about easily accessible information for application servers, such as monitoring data, is surprising" he notes.
Application servers have emitted useful monitoring data and provided basic management capabilities for years, but both capabilities have been ignored. The DevOps movement is making these built-in monitoring and management capabilities interesting again.
The article describes the GlassFish management API, which allows you to manipulate the GlassFish application server's configuration, including its monitoring capabilities. It also describes the GlassFish monitoring API, which provides a read-only facility for accessing the Java Virtual Machine (JVM), the GlassFish application server, and the GlassFish application server's metrics and counters.
