Conditional logging
Can anyone point me to an example of conditional logging in Tomcat 6? Here is what I have tried to no avail. I want requests that match /*/iaahb to not be logged.
In my server.xml:
<Valve className="org.apache.catalina.valves.AccessLogValve"
condition="DoNotLog"
directory="logs"
fileDateFormat="yyyy-MM-dd"
pattern="%{X-Forwarded-For}i %h %l %u %t "%r" %s %b "%{Referer}i" "%{User-Agent}i""
prefix="access_log"/>
in my web.xml:
<!-- Custom filter to prevent logging health check requests -->
<filter>
<filter-name>Set Do Not Log Attribute</filter-name>
<filter-class>SetDoNotLogFilter</filter-class>
<init-param>
<param-name>DoNotLog</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Do Not Log Attribute</filter-name>
<url-pattern>/*/iaahb</url-pattern>
</filter-mapping>

I have not explored this, so these comments are based on the
documentation.
http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access_Log_Valve
Turns on conditional logging. If set, requests will be logged only
if ServletRequest.getAttribute() is null. For example, if this
value is set to junk, then a particular request will only be
logged if ServletRequest.getAttribute("junk") == null. The use of
Filters is an easy way to set/unset the attribute in the
ServletRequest on many different requests.
So . . .
1. multiple URL patterns to add an attribute - exclude /*/iaahb
2. rewrite the filter to:
a. examine the URI
b. add the attribute if it does not include /*/iaahb
c. set the URL pattern to /*
3. Use tuckey.org's URL rewrite filter (http://tuckey.org/urlrewrite/)
a. use a negative regular expression match
b. set the attribute value for all URI patterns except /*/iaahb
. . . just my two cents

The url-pattern syntax defined by the Servlet specification is
somewhat limited. The "*" has special meaning in two constructs only:
a) when defining prefix mapping, as "/*" at the end, e.g. /foo/*
b) when defining extension mapping, .e.g. *.foo
In all other situations the "*" character is interpreted literally as
a character, with no special meaning.

Please don't hijack threads. If you have a question, please create a
new email message to users@tomcat.apache.org, give it a new subject,
and don't address it to a single person (like me). This is a community
and not a one-on-one help desk.

Chris,
Quick question, I upgraded to 7.0.54 with new user/pass. My issue is that these credentials will not log me in to ANY management function going through the GUI??? If I append the WEBAPP
Tho the url http://localhost\web app name this launches the app - but still I need to access all CmcApps via the GUI. Any ideas?

On the face of it, this looks like it should work. What does your "SetDoNoLogFilter" code look like?

The

be allowed or suppressed. The "conditionIf" and "conditionUnless" are
much more straightforward.

As Mark Eggers already said: you can also use the Tuckey
UrlRewriteFilter to set the chosen request attribute "DoNotLog" for you.
See for example
http://urlrewritefilter.googlecode.com/svn/trunk/src/doc/manual/4.0/index.html#set
I haven't tried it but something like
<rule>
<from casesensitive="true">^/[^/]*/iaahb$</from>
<set name="client">DoNotLog</set>
</rule>
Note that for TC 7 there's also a conditionIf and conditionUnless, which
makes it a bit easier, if you need to revert the logic:

Yes, I was hoping for a little magic. Conditional logging seems like such a basic concept that I am greatly surprised to have to jump through hoops to achieve it. The documentation I've read for filters seems to be intended for an audience with prior webapp development experience. Unfortunately I do not fall into that crowd, so I was unaware a filter had to be related to another piece of configuration/code. I am looking into the url-rewrite filter as suggested. Thanks!

Hah. Okay, so then what does "SetDoNotLogFilter" refer to? Or were you
just hoping that would magically work?
Mark's response was prescient: you probably want to use the

Perhaps that's my problem, I do not have any code to support this. I think for this to work as I have it now I need an existing Java filter class.

On the face of it, this looks like it should work. What does your
"SetDoNoLogFilter" code look like?
