Nick Williams commented on LOG4J2-241:
--------------------------------------
I struggled with trimming (and its inconsistency) in Log4j 1's PatternLayout a
great deal back in the day. IMO, any pattern element that can be trimmed from
one direction should also be able to be trimmed from the other. There are
always reason for either use case.
> Support the ability to trim logger name from the right.

> Reporter: Kurt Lehrke
> Priority: Minor

> In log4j2, there doesn't seem to be a way to trim the logger name from the
> right. I have a situation where our logger names can be extremely large,
> even when only using the class name. We'd like to trim it down to a certain
> number of characters (e.g. 10). When reading trace files, the 10 beginning
> characters would be more unique than the last 10 characters. This would be
> extremely useful for us to be able to do in the configuration file in the
> pattern layout.
