[logback-user] How to programmatically find an appender for a logger?

[ceki]

Hi Johannes,

I think the fact that you cannot fetch all the appenders 
registered/active in system is a shortcoming in the API. You are also 
correct to point out that one cannot easily obtain the parent of a 
logger. Please create a jira issue requesting these operations be added.

TIA,
