Subject Re: Is it possible to log IP Address of requestor with custom AccessLogValve pattern?
Date Tue, 31 Oct 2006 03:13:31 GMT
Hi Li, 

I'm sorry I should have re-referenced the AccessLogValve documentation earlier. 

I can still get this to work with the AccessLogValve custom pattern itself by adding the request
header in this
pattern element %{xxx}i , where xxx is the request header.

The following also worked, as shown below:

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" 
 pattern="%{x-forwarded-for}i; %H %u %t &quot;%r&quot; %s %b &quot;%{Referer}i&quot;
&quot;%{User-Agent}i&quot;" 
 prefix="localhost_access_log." resolveHosts="false" suffix=".txt" />

May be this kind of setup will slow down the performance of the site, but I'll probably disable
the logging after getting an initial sample of search engine bots.

Thanks for your suggestions and help, I will keep those in mind. I still need to learn Log4J
and logging in general. 

But for now, this setup is sufficient.

-Regards
Rashmi

Hi Rashmi,

You can creater your own log handler and pack it as jar and put it under
tomcat lib dir, modify the loggin.properties file to have your handler work.

Also, you can create your own request processor or intercepter to retrieve
source ip from header and pass to logger.

Regards
