I'm another happy, impressed LOGBack user who has very similar needs. Where
I develop, we have several different deployment levels, all of which require
substantially different logging configurations (e.g., development, qa, staging,
production). However, our standard rollout procedure currently produces one
standard build, as a zip file, for QA and above. We control the configuration
in our startup with a few environment variables.
As I start to push for my team's adoption of LOGBack, some mechanism like
the one proposed below will be essential. I can't see any reason why I couldn't
include a base logging configuration file in the classpath as a springboard to
the configurable logging location. It would be convenient to specify the
location for quick-and-dirty hacks, but I could live without it. The only
drawback is that Log4j offers this, so there may be some in my group who
protest changing to an implementation they may call +IBw-incomplete.+IB0 That said, if
I could only have one, it would definitely be the inclusion mechanism.
I+IBk-m not yet familiar with Joran, but it would be great if we could include
some configure kind of mapping that along the lines of the below (pidgin
pseudocode, but I think it's pretty clear).
+AKAAoACg logName =
+AKAAoACgAKAAoA case ENV{'env'} of+AKAAoACgAKAAoACgAKA 'qa'+AKAAoA -> 'qa-logback.xml'
+AKAAoACgAKAAoACgAKA 'dev'+AKA -> 'log-dev.xml'
+AKAAoACgAKAAoACgAKA 'prod' -> 'logback.xml'
+AKAAoACg logLocation = concat(ENV{'root'}, '/config/', logName)
As long as I can control the location of the file with an environment
variable, I can make things work, but it would be great to make the file
location a function of one or more variables as above.
Thank you,
Andy Gerweck

Hi Michael,
What you propose makes sense. However, I'd like to limit
the number of ways
logback can be configured (to ease the brain-footprint of
logback on our
users.) How about if we allowed a config file to include
parts from a
different sources? This inclusion feature should allow
you to reference a
different file. Moreover, since Joran supports variable
substitution, you
could set the value of the variable through a system
property. You would
get the feature you are asking for, and we would keep the
initialization
procedure simple (err, simpler.).
WDYT?
If you agree, could you please file a bug report asking
for inclusion
feature in joran/logback?
