RE: Piping log messages to different appenders via LEVEL

[Jesper Lund Stocholm]

Hi Ross,

 

Thank you very much - it now works like a charm. Looking at the SDK
(again), I now realized that the object model mirrors the configuration
template (or vice versa). Moving the <Threshold>-element "up" solved the
problem. I dropped the <evaluator>-element from my RollingFileAppender
at the same time.

 

Thanks for your input :o)

 

 

Med venlig hilsen / Best regards

You should be able to use the Threshold tag under the appender to
specify what level you'd like to start logging.  The threshold is
inclusive.

The log4net SDK outlines how it works:
http://logging.apache.org/log4net/release/sdk/log4net.Appender.AppenderS
keleton.Threshold.html

I've modified your configuration below; I think it's correct.  Let me
know if you have trouble with it.

I would like to send log messages to one of two appenders depending on
the level of the message. Specifically, I'd like this:

 

Everything: send to Console

Error and above: send to file

 

So I have configured these two appenders:

 

<appender name="Console" type="log4net.Appender.ConsoleAppender"> 
         <threshold value="ALL" />

            <layout type="log4net.Layout.PatternLayout">

              <conversionPattern value="%date %-4timestamp [%thread]
%-5level %logger %ndc - %message%newline" />

            </layout>

        </appender>

         

        <appender name="RollingFileAppender"
type="log4net.Appender.RollingFileAppender">
          <threshold value="ERROR" />

          <file value="C:\Windows\Temp\servicelog_01.txt" />

          <appendToFile value="true" />

          <lockingModel type="log4net.Appender.FileAppender+MinimalLock"
/>

          <rollingStyle value="Size" />

          <maxSizeRollBackups value="10" />

          <layout type="log4net.Layout.PatternLayout">

            <conversionPattern value="%date %-4timestamp [%thread]
%-5level %logger %ndc - %message%newline" />

          </layout>

          <evaluator type="log4net.Core.LevelEvaluator">

            <threshold value="ERROR"/>

          </evaluator>

        </appender>

         

        I would have thought that adding the <evaluator>-element to the
RollingFileAppender would filter the messages only saving the messages
with level "ERROR and above", but everything still gets send to both
appenders.

         

        Can you tell me what I am missing here?

         

        Thanks,
