ColoredConsoleAppender

The ColoredConsoleAppender writes log messages to the console with color coding based on log levels. It allows configurable colors for each log level, making it easier to identify log severity.

The following example shows how to configure the ColoredConsoleAppender to log messages to the console. This example shows how to highlight error messages.

<appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
  <mapping>
    <level value="ERROR" />
    <foreColor value="Red, HighIntensity"/>
  </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="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
  <mapping>
    <level value="ERROR" />
    <foreColor value="Red, HighIntensity"/>
  </mapping>
  <mapping>
    <level value="DEBUG" />
    <foreColor value="LightGray" />
  </mapping>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
  </layout>
</appender>
