add new log appender dynamically to org.ops4j.pax.logging at run
time
*Hi;*
I am curious what is the right way to
add new log appender dynamically to org.ops4j.pax.logging at run time
that is, NOT programmatically, but from a sibling config file such as
${karaf.base}/etc/org.ops4j.pax.logging-extra.cfg
?
I can not find this feature in the source, must be looking in the
wrong place :-)
use case: AWS SNS based appender should be activated/deactivated on
demand;
http://aws.amazon.com/sns/
Thank you,
Andrei

Hi Andrei,
You could add a new log appender (JMS, ....) as a bundle. This appender
should implements the interface PaxAppender of Pax Logging and registers a
service. I have created yesterday a JMS Appender for ActiveMQ that we will
use on ServiceMix. Depending when you have to use it or not, you could stop
/ start the bundle exposing a Pax Loggin OSGI Service.
Another solution is maybe to use the camel paxlogging component (
http://camel.apache.org/pax-logging.html) in combination with your
camel-aws and a trigger pattern to decide when you must send or not / log
or not.
