FusionReactor captures web requests into the application server allowing you to track the rate of requests (via activity / time graphs) and the exact URLs being hit (via the active / history pages)
Web Requests which error, are slow or have errors are tracked into individual lists.
Track down memory usage of the JVM and track down which transactions are allocating the most.
FusionReactor shows detailed information about the configured garbage collector your JVM is using and shows how much memory is being freed and how often.
If the Web Request or Transaction contains any JDBC queries e.g. SQL, Hibernate, MongoDB etc. then detail information will be displayed – such as the exact SQL statement executed, number of rows returned, time taken to execute etc.
These are tracked into individual lists based on whether they error or are slow.
Java Management Extensions (JMX) / MBeans includes 100’s of metrics relating to resources running inside the JVM
