I think what you want to do is use the logger heirarchy for this.
Something like the following will work:
 
<log4net debug="true">
  <appender name="VerboseAppender" type="...">
    ...
  </appender>
  <appender name="DBAppender" type="...">
    ...
  </appender>
  <appender name="NamespaceClassApppender" type="...">
    ...
  </appender>
  <root>
    <level value="ALL"/>
    <appender-ref ref="VerboseAppender"/>
    <appender-ref ref="DBAppender"/>
  </root>
  <logger name="MyNamespace.StaticClassX" additivity="false">
    <level value="ALL" />
    <appender-ref ref="NamespaceClassAppender" />
  </logger>
</log4net>


The key here is the additivity="false" attribute on
MyNamespace.StaticClassX logger.  This indicates that the logger doesn't
inherit appenders and other settings from the root logger, so messages
sent to that logger are only sent to NamespaceClassAppender and not
VerboseAppender or DBAppender.

Hi peoples,

 

I've used log4net for a while, but I've got the following problem.

 

I have a rolling file appender that takes everything, we'll call this
the "VerboseAppender", easily configured.  ALL levels go to it and
everything gets logged.

 

I have an ADO.Net appender that takes ERROR,FATAL level and logs to a
stored procedure. We'll call this the "DBAppender"

 

But, we've got an annoying set of printer classes, that tend to spew
masses of errors sometimes. These live under MyNamespace.StaticClassX.

What we need to do is add a separate local rolling file appender
"NamespaceClassApppender", that takes only logs messages from
MyNamespace.StaticClassX and logs them.

Then I need exlcude anything for MyNamespace.StaticClassX from the
VerboseAppender and the DBAppender.

 

Is the best way to do this with Filters?

 

Basically each appender needs the following?

VerboseAppender, IF you're NOT MyNamespace.StaticClassX  log it

DBAppender,  (same as above)

NamespaceClassApppender, IF you ARE MyNamespace.StaticClassX log it,
otherwise ignore it.

 

Thanks in advance.

Hadley
