Also you can configure Apache to log the value of the
session cookie (if you're using session cookies --
LogFormat "%{JSESSIONID}C..."), which includes the lb
route so that you even know which instance of Tomcat
took the request.
... and finally once we release the next mod_jk version (soon), there is
even more info from the load balancer worker available for logging in
the usual Apache access log. Information available includes the target
worker chosen by the load balancer, it's load values, error states etc.
One reason for additional access logging in tomcat would be, if you've
got performance problems and want to measure response times directly in
the web container.
Another reason with mod_jk including the latest officially released:
you've got session problems and want to track, which container instance
your request went to. Using the Cookie in the apache access logs is OK,
but in case the load balancer has a worker in error state, you wont
recognize, that the requests haven't been handled sticky.

If apache is serving all the traffic - then tomcat
doesn't need to
record any access logs. (Unless you need monitor how
much load went to
each tomcat) Apache will have every request. If you
combine the logs -
you would double count some of your requests.

Hello,
for a project I had to set up an environment with
Apache2, mod_jk and 2 Tomcat
instances. Apache2 / mod_jk will route requests to
Tomcat1 and Tomcat2 (load
balancing).
How can I install a log analysis tool like AWstats
into this environment?
I mean which log files should I use, Apache2-log,
Tomcat1-log or Tomcat2-log?
Can I combine them all together?
