Re: Running Karaf without PAX Logging
Is there any ongoing effort for a Logback backend to Karaf?
I can only find rather old messages in this regard.
Thanks,
Sam

To my understanding there is no such effort,
but you are invited to provide such a backend to pax logging :)

Re: Running Karaf without PAX Logging

The logback site has a page dedicated to reasons for switching:
http://logback.qos.ch/reasonsToSwitch.html
An argument for logback in our project is performance. Since audit logging
requirements for us are very high, logging enters into that calculation.
Considering that this is the original developer of log4j (he is the
principal author on both projects) claiming significant performance
improvements for logback over log4j, I think the statement carries some
weight.
With regards to configuration, logback can be configured programmatically:
http://mailman.qos.ch/pipermail/logback-dev/2009-February/003785.html
http://mailman.qos.ch/pipermail/logback-dev/2009-February/003785.html
http://logback.qos.ch/manual/joran.html
http://logback.qos.ch/manual/joran.html
http://logback.qos.ch/joran.html http://logback.qos.ch/joran.html
As to implementing this ourselves, I am afraid our project is under too
strict time constraints for this to be possible (also considering that we
are just getting to know karaf). Except if, given the programmatic
configuration possibilities, this would in fact be quite straightforward?
Thanks,
Sam

After I checked back with the original Author of this appender [1] I have an
OK for it :)
So I'll try to add this appender[2] as soon as possible to pax-logging.

Maybe we should include your appender by default in pax-logging ? It sounds
quite useful to me.

Well, the only thing i would like to have would be the appender that already
does the zipping of roled over log files.
But this can be easily done with a custom appender and I wrote a blog [1]
about it how to attach it to karaf, so no
real need to actually get it into pax-logging ;)

Re: Running Karaf without PAX Logging
Posted by Guillaume Nodet <gn...@gmail.com>.
The main problem I see with logback is that there's no properties based
configuration for logback.
That's a real problem imho because we would not be able to leverage the OSGi
ConfigAdmin which is a key point in order to have a clean interaction point
with all configurations. If you are aware of anything that would look like
a properties based configurator for logback, things may changed.
That's said, I've still haven't heard any real reasons to swtich to logback.
The version of log4j that is embedded in pax-logging has been enhanced to
fix some over synchronization problem (leading to performance issues) and
also to add the features that were needed (like a split appender, etc...).
What need do you have for logback ?
