Glassfish monitoring basically deals with the collection of metrics such as throughput, Disk I/O, memory usage and CPU utilization. Thus, it refers to the different tools and approaches for tracking the performance of web and application servers. Though it helps you to manage infrastructure, it lacks the ability to isolate and resolve issues in the application code.
AppDynamics possess the capability to discover automatically business transactions from usual access points in GlassFish and its JVM like as struts actions, servlets, web services callsspring MVC, and even custom POJO access points. This enables users to see how business transactions perform through remote calls across CLR and JVM for distributed transactions and various Java components like JDBC, SOAP, EJB, CICS, JMS.
AppDynamics notifies support teams about performance issues before it affects end users and service levels begin to breach through dynamic SLA base-lining and pro-active alerting.
AppDynamics auto-tracks memory leaks inside the GlassFish Server and its JVM. It provides superior view of garbage collection, heap usage and using key memory pools and thereby helps find the root cause of memory leaks within minutes.
