Metrics

These metrics are collected directly from the platform MBeans exposed by the JVM that executes the JBoss instance. A JMX connection is required, but the same JMX connection can be used to collect JBoss-level and application-level metrics.

JVM Memory Metrics

There is a certain degree of overlap between the information provided by the memory-related platform MBeans and the garbage collection log.

Platform MBeans:

JVM Thread Statistics

Platform MBeans:

O/S Level Runtime Metrics

Platform MBeans:

Classloading Metrics
