ManagedColoredConsoleAppender

The ManagedColoredConsoleAppender writes log messages to the console with colored output. It provides more control over the colors used for different log levels.

The following example shows how to configure the ManagedColoredConsoleAppender to log messages to the console. By default the messages are sent to the console standard output stream.

This example shows how to highlight error messages.

<appender name="ManagedColoredConsoleAppender" type="log4net.Appender.ManagedColoredConsoleAppender">
  <mapping>
    <level value="ERROR" />
    <foreColor value="White" />
    <backColor value="Red" />
  </mapping>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
  </layout>
</appender>

This example shows how to colorize multiple levels.

<appender name="ManagedColoredConsoleAppender" type="log4net.Appender.ManagedColoredConsoleAppender">
  <mapping>
    <level value="ERROR" />
    <foreColor value="DarkRed" />
  </mapping>
  <mapping>
    <level value="WARN" />
    <foreColor value="Yellow" />
  </mapping>
  <mapping>
    <level value="INFO" />
    <foreColor value="White" />
  </mapping>
  <mapping>
    <level value="DEBUG" />
    <foreColor value="Blue" />
  </mapping>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %-5level %logger - %message%newline"/>
  </layout>
</appender>
