I built an appender that buffers messages and it will write the content to the appender on the stop method. With this appender I want to collect messages that are related to a specific Object instance in my application. For example; I want to collect all messages that belong to one ProcessingRequest. Once this request is completed I want to flush it out to a Space as one string plus host and some more info.... I noticed that the appender does not exist any more after I call the stop method. Furthermore it looks like appenders are not created on a per logger basis, there seems to be just one appender instance .... Is there a way to force a new appender instance for each logger ?
