-------------------------------------
Thanks Ralph. I made some progress today.
Actually, Flume uses SLF4j. So I configured log4j-slf4j binding (log4j2) and
after some struggle with dependency cleanups, I was able to get some agent logs
to the file (given below).
However, the above (startup) logs still doesn't show up. Now it has disappeared
from console as well.
My log4j2 configuration now is
<Root level="ALL">
<AppenderRef ref="applicationFile"/>
</Root>

> Where can I view the embedded flume agent startup logs

> Key: LOG4J2-789
> URL: https://issues.apache.org/jira/browse/LOG4J2-789
> Project: Log4j 2
> Issue Type: Question
> Components: Flume Appender
> Affects Versions: 2.0-rc2
> Reporter: Bijith Kumar
>
> Question is about the INFO/ERROR statements logged by the embedded flume
> agent during startup.
> When running from eclipse I am able to see these logs in the console.
> However, when deployed in Tomcat, the log doesn't appear in application or
> catalina.out logs. I tried adding the below configuration in my log4j2.xml
> but that didn't work either
> <Logger name="org.apache.flume" level="INFO">
> <AppenderRef ref="applicationFile" />
> </Logger>
> Just to make it clear, I am talking about the below logs (i.e.the embedded
> agent startup logs)
