[logback-user] How can I monitor the actual size of the asyncappender queue?

[haobo liu]

maybe ch.qos.logback.core.AsyncAppenderBase#getNumberOfElementsInQueue
 or hack the code add a volatile variable (bad idea)

I did notice there is a "listener" mechanism, and one example I believe illustrates how I can detect when logs are dropped because the queue is full, but I want to get an idea of how well the queue size is being utilized, or how close it's getting to being full.
