Using Camel & Log4j on Multiple Machines
I am current logging everything using log4j directly to files on the local
machine. Now that I am using Camel and going across multiple machines, I
would like my logs to remain on each local machine, but anything above
warning to also go to a designated machine.
I was wondering if anyone did this and what was their approach.
I could do it all directly with log4j & sockets. But why not use
Camel/ActiveMQ. I was wondering if it would be better just to extend the
loggers for this, or to build an appender which would push the messages back
into a topic?
Any advice?
Thanks.

In case you deploy camel in karaf, camel already defines a custom
pax-logging appender which intercepts all log events (slf4j, log4j,
jul, jcl) and can process them.
See http://camel.apache.org/pax-logging.html

Yeah this can be tricky as you would have different classloaders and whatnot.
Also the log4j could be shared among different Camel applications.
You can use a remote transport of some sort, and send data over HTTP.
However if you run in Karaf, then pax-logging, may have some osgi
related stuff you can leverage.

Re: Camel Log4j Appender

Creating a custom log4j appender is very easy (... indeed we have one but we
are not happy with it as it only injects into ActiveMQ and not into a Camel
route).
Our only problem (and this is now turning into a developer question more
than a user question) is how can the custom Appender which is a part of the
log4j hierarchy get a reference to a route producer template?
If we for example
1. Configure an instance of the custom appender and using the
log4j.properties / log4j.xml file configure it to inject into the route
"direct:logs".
2. Configure a Camel route 'from("direct:logs").to("activemq:topic:logs)'
How do we in the log4j Appender get a reference to the ProducerTemplate with
the identifier 'direct:logs'?

Yeah I think log4j has a plugin API for appenders.
You should check log4j documentation.
And as you know we love contributions so if you go about developing
such an appender, then consider donating it to Apache.

Camel Log4j Appender
Posted by Gert Villemos <gv...@yahoo.de>.
Did this issue moved forward?
I can find a log4j JMS logger that can inject data into an ActiveMQ, but I
would like to inject events into a camel route which might go to ActiveMQ,
but might also have other steps.
Can this be done?

Good idea :)
I guess we could write a log4j appender that takes a Camel URI to
route to? Folks could even use a Content Based Router if they wanted
to etc.
