Write logs to separate file in Umbraco 6+

Hi guys,

I know Umbraco uses Log4net behind the scene and the config is in log4net.config. Is it possible to log my entries to a separate file as UmbracoTraceLog is getting bloated and it's quite difficult to track my log there?

Thank you.

I've seen this post: http://blog.darren-ferguson.com/2013/02/22/log4net-logging-from-your-custom-code-in-umbraco/ And I've set up my custom logger and appender, but I still get all Umbraco logs logged to my new file.

My log4net.config looks like this:

<?xml version="1.0"?>
<log4net>
    <root>
        <priority value="Info"/>
        <appender-ref ref="AsynchronousLog4NetAppender" />
    <appender-ref ref="CustomAppender" />
    </root>

    <!--To Change the way logging works for certain namespaces, insert a new logger like: -->
    <!--
    <logger name="Umbraco.Core">
        <level value="WARN" />
    </logger>-->

  <logger name="My.Namespace.Web">
    <level value="DEBUG" />
    <appender-ref ref="CustomAppender" />
  </logger>

  <!-- Native Umbraco appender-->
    <appender name="AsynchronousLog4NetAppender" type="Umbraco.Core.Logging.AsynchronousRollingFileAppender, Umbraco.Core">
        <file value="App_Data\Logs\UmbracoTraceLog.txt" />
        <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
        <appendToFile value="true" />
        <rollingStyle value="Date" />
        <maximumFileSize value="5MB" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
        </layout>
    </appender>

  <appender name="CustomAppender" type="Umbraco.Core.Logging.AsynchronousRollingFileAppender, Umbraco.Core">
    <file value="App_Data\Logs\Custom.log.txt" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <appendToFile value="true" />
    <rollingStyle value="Date" />
    <maximumFileSize value="5MB" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
    </layout>
  </appender>

</log4net>

Is there anything wrong with my config?

Cheers

I figured this out,

I had to remove <appender-ref ref="CustomAppender" /> from <root>

change <appender name="CustomAppender" type="Umbraco.Core.Logging.AsynchronousRollingFileAppender, Umbraco.Core">

to <appender name="CustomAppender" type="log4net.Appender.FileAppender">

Then in my code:
```
private static readonly ILog log = LogManager.GetLogger("MyLogger");
log.Info("Log info");
```
