Hi,
After attempting to have a flume log4j appender but couldn't make it work as
discussed as part of this thread..
http://karaf.922171.n3.nabble.com/Enabling-Flume-log4j-appender-logging-in-Karaf-td4036033.html#a4036041
and not knowing how to further debug the same.. thought of trying the
pax-logback-service followed by using the logback-flume appender and I have
done the configuration as documented for pax-logback-service -- still I
don't see the karaf.log populated.. The last thing I see in karaf.log is as
shown below and nothing else.. Please provide any knobs that I can turn on
to debug this in Karaf. I have included the configuration I did below..

1. When I check pax-logback service status it shows as Active as shown
below..
bundle:list |grep Logback
8 | Active | 8 | 1.7.2 | OPS4J Pax
Logging - Logback Service
2. My org.ops4.pax.logging.cfg looks like this

org.ops4j.pax.logging.logback.config.file=${karaf.base}/etc/logback.xml
3. My logback.xml looks like this ..
<?xml version="1.0" encoding="UTF-8"?>

4. my etc/startup.properties looks like this...
