Access Valve
Hi,
I am trying to set up the access valve so that we can analyze our
traffic using the softwares that are out there.
I noticed that when I turn on the access valve, it logs requests for
every little item on the page, all the images etc. Is there a way I can
have tomcat log only one line for every session? Or is there a way to
exclude requests made for images and certain other types of files?
Thanks,
-Rizwan Merchant.

No, Chris was talking about the configuration of the AccessLogValve.
Read the documentation link he gave.
Alternatively, maybe you can just grep the log file for certain lines
that tell you what you need to know, for example "GET /index.jsp".

Well, you could install a simple filter to add this attribute: you don't
have to modify your application's code.

That depends. Are you observing a performance problem?

As long as you're not suffering from premature optimization, turning
"down" the access filter will speed things up. Then again, logging is
fast when compared to something like database access. If you have a
relatively heavy application, logging isn't likely to be a big
performance problem.

Thanks Chris,
Does that mean that I need to set the value of an attribute in my code,
and check that value in the valve? That seems intrusive as I have to set
up my code to handle this.
Let me step back a little. Can you tell me..what if I leave it the way
it is and let it log everything. Would this slow down the application
since it will be doing a LOT of writing to the access log file? Or am I
worrying too much about this?
My main reason to log less is so that tomcat is not bogged down because
of how much it is writing to the access log..
Thanks,
-Riz.

One line for every session? Or one line for the first request processed
by a keepalive connection?

It looks like the only way to do either of these things is to use the
"condition" attribute of the valve. Check out the docs for that
attribute -- it might give you some ideas.
