Internal
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:
- Memory MBean
- Memory Pool MBeans (these depend on the JVM version and the type of garbage collector in use).
- Garbage Collector Memory Manager MBeans (these depend on the type of garbage collection in use).
- Various thread counts obtained from Thread MBean.
