Is there any way to monitor the task queue of scala.concurrent.ExecutionContext.Implicits.global? ie., see the number of tasks waiting for a thread to be released?
回答1:
JDK comes along with jconsole and jmc. You can use them to see thread usage. You can see,
- Thread state,
- blocked count
- thread allocated bytes etc
scala implicit threads name start with scala-execution-context-global-n.
