Total number of blocked and waits in Jconsole threads Panel (RPM)

Total Blocked

Blocked count is the total number of times that the thread Blocked to enter or reenter a monitor. i.e. the number of times a thread has been in the Java.lang.Thread.State.BLOCKED state.

Total Waits

Waited count is the total number of times that the thread waited for notification. i.e. the number of times that a thread have been in the Ava.lang.Thread.State.WAITING or Java.lang.Thread.State.TIMED_WAITI NG state.

When a thread attempts to acquire an internal object lock (not a lock in the Java.util.concurrent Library), and the lock is occupied by another thread, the thread goes into a blocking state.

When a thread waits for another thread to notify the scheduler of a condition, it enters its own wait state. A wait condition occurs when you call the object.wait () or Thread.Join () method, or wait for lock or condition in the Java.util.concurrent library
