Enable the JVM debugging options to track garbage collection data for the system. These options can impact JVM performance, but provide valuable data to tune the server. While the jstat utility with the -gc option can be used to obtain some information about garbage collection activity, there are additional arguments that can be added to provide additional detail, such as:
-XX:+PrintGCDetails
-XX:+PrintTenuringDistribution
-XX:+PrintGCApplicationConcurrentTime
-XX:+PrintGCApplicationStoppedTime
-XX:+PrintGCDateStamps
