Question by Nick R. · Sep 09, 2015 at 12:31 PM ·

Thread/Thread Pool Metrics?

I'm at a customer and I've been asked a question regarding the Thread/Thread Pool metrics and I don't know the answer.

Please can I get some clarification as to what the following metrics mean?

  1. Thread Count (I understand this one)
  2. Thread Pool Current Thread Count
  3. Thread Pool Current Threads Busy

Thanks,

Nick

Hi Nick

my guess is that thread count is the total number of threads created by the application server for everything (internal threads and application threads).

Thread pool could be more specific. With oracle weblogic for instance, you can have work managers which allow you to pin parts of the application to them so they run against dedicated threads.

I'm guessing it might be something similar but it depends on the application server.

The different between count and busy is fairly obvious. The count is the total number of thread (active or waiting for work) and the busy thread are only active.
