Finding Thread Activity and Memory Usage JBoss EAP 4.x

Solution Verified - Updated -

Environment

  • JBoss Enterprise Application Platform (EAP)
    • 4.2
    • 4.3

Issue

  • For a given JBoss instance, how do I find the following:
    • Thread usage
    • Thread CPU
    • What each thread is meant for and what kind of work it's doing
    • Memory consumed by each thread

Resolution

  • You should be able to get all those information by going to jmx-console (e.g.: http://localhost:8080//jmx-console/HtmlAdaptor) and apply this filter:
jboss.system:type=ServerInfo,*
  • Click the link type=ServerInfo and there will be several operations you can invoke:
    • listThreadCpuUtilization()
    • listThreadDump()
    • listMemoryPools()
