Linbo, "currentThreadsBusy" is number of busy threads. These are the threads are being actively use. If you are seeing this count > 0 for long time(depending on your application type), then most likely you have "hung thread". In that case thread dump analysis will show you root of the problem.
"currentThreadCount" is current threads in thread pool. To track thread pool usage, you can use this counter. Thanks!
