LocalSyslogAppender

LocalSyslogAppender writes messages to the local syslog service on Unix-like operating systems. It uses the system’s native syslog daemon and does not support remote logging.

The following example shows how to configure the LocalSyslogAppender. It sends all events with Level WARN or higher.

<appender name="LocalSyslogAppender" type="log4net.Appender.LocalSyslogAppender">
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date{MM/dd/yyyy HH:mm:ss.fff} [%thread] %-5level %logger - %message%newline" />
  </layout>
  <threshold value="WARN" />
</appender>

You can also specify:

Facility (default: user)
Identity (default: application name)

<appender name="LocalSyslogAppender" type="log4net.Appender.LocalSyslogAppender">
  <facility>Alert</facility>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date{MM/dd/yyyy HH:mm:ss.fff} [%thread] %-5level %logger - %message%newline" />
  </layout>
  <identity>MyApp-Canary</identity>
  <threshold value="WARN" />
</appender>
