I've installed Glimpse on umbraco to trace performace and I got it working. The problem is that the normal logging stopped.

My log4net.config looks like this now

<?xml version="1.0"?>
<log4net>
  <root>
    <priority value="Info" />
    <appender-ref ref="AsynchronousLog4NetAppender" />
  </root>
  <!--To Change the way logging works for certain namespaces, insert a new logger like: -->
  <!--
    <logger name="Umbraco.Core">
        <level value="WARN" />
    </logger>-->
  <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>
    <encoding value="utf-8" />
  </appender>
  <appender name="GlimpseAppender" type="Glimpse.Log4Net.Appender.GlimpseAppender" />
  <root name="glimpse7">
    <level value="ALL" />
    <appender-ref ref="GlimpseAppender" />
  </root>
</log4net>

I figure that having multiple root will not work well.

Tried to look up how to change so that both glimpse and standard logging works, and I should move

<appender-ref ref="AsynchronousLog4NetAppender" />

to the second root and remove the first. But then all message will be logged, and that I don't want.

I guess I should be able to specify in the appender AsynchronousLog4NetAppender what level it should run at, and the same for the glimpse?

Some points to having a seperate logger tag, but then I need to specify when to use it so thats no good.

I've seen posts that specify to set a filter in the "standard" appender

<filter type="log4net.Filter.LevelRangeFilter">
            <levelMin value="INFO" />
            <levelMax value="FATAL" />
</filter>

I'm not sure if this will affect performance? Is there anyone that can point me to best practice?
