How do I make Log4net only log Info level logs? Is that even possible? Can you only set a threshold?
This is what i have, and it logs Info and above as i would expect. Is there anything i can do to make it only log info.
<logger name="BrokerCollection.Model.XmlDocumentCreationTask">
<appender-ref ref="SubmissionAppender"/>
<level value="Info" />
</logger>
Hmm, I haven't come across a specific log level before, just the threshold type items. Is there a particular reason you want just INFO level logging, or would it be beneficial to setup a seperate appender for your INFO level logging to go to a seperate file or database?
You should be able to setup multiple root tags to configure each level you desire. So you can have a ...
<root>
<level value="ERROR" />
<appender-ref ref="XmlSchemaErrorFileAppender" />
</root>
...which will log all ERROR and FATAL messages to a file and then a second...
<root>
<level value="ALL" />
<appender-ref ref="XmlSchemaGeneralFileAppender" />
</root>
... which will log everything to a different file. If for some reason the multiple root tags don't work (it has been a while since I've done this), then you strip out the root tag and you setup individual logger tags for each class in your application and can configure accordingly.
Is this closer to what you're looking for?
No, sorry that will create 2 files one with all logs and another with Errors and above.
Im thinking what im wanting is not possible, log4net is excellent but its only ment for one reason, application logging.
Within the definition of the appender, I believe you can do something like this:
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="INFO"/>
<param name="LevelMax" value="INFO"/>
</filter>
...
</appender>
Yes. It is done with a filter on the appender.
Here is the appender configuration I normally use, limited to only INFO level.
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="${HOMEDRIVE}\\PI.Logging\\PI.ECSignage.${COMPUTERNAME}.log" />
<appendToFile value="true" />
<maxSizeRollBackups value="30" />
<maximumFileSize value="5MB" />
<rollingStyle value="Size" /> <!--A maximum number of backup files when rolling on date/time boundaries is not supported. -->
<staticLogFileName value="false" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date{yyyy-MM-dd HH:mm:ss.ffff} [%2thread] %-5level %20.20type{1}.%-25method at %-4line| (%-30.30logger) %message%newline" />
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="INFO" />
</filter>
</appender>
If you would like to perform it dynamically try this:
