Ok, then the next question is how do I access this from code? I see that Logger's base hierarchy has a "getAppender(String)" method. What is the input parameter for that? Once I solve that, I guess I have to think about whether it makes sense to write occasional log messages that print the current queue size (which would obviously go into the queue). I wonder if I can render it in a JMX property? > KARR, DAVID <dk0...@att.com> 于2021年5月28日周五 上午12:02写道： > > > > I believe I now understand the basic mechanics of the AsyncAppender > queue, and the tradeoffs of having it small or large. > > > > What's not obvious to me is how I can monitor the utilization of the > queue, perhaps in a load test.
