Liberty profile: ThreadPool monitoring

You can use a ThreadPool MXBean for thread pool monitoring in the Liberty profile.

All Web Requests executes in the thread pool, named Default Executor thread pool. You can monitor the usage of Default Executor thread pool using ThreadPoolMXBean.

The ObjectName for identifying MXBean for thread pool is :
WebSphere:type=ThreadPoolStats,name=Default Executor
Key Performance data available for ThreadPool are:
  • Threads in the pool which represents the pool size.
  • Active threads which are serving requests.
Attributes for ThreadPool
  • ActiveThreads
  • PoolSize
  • PoolName (Only supports Default Executor thread pool)
.
