Logging Config File Samples

combo1_log.config

This example shows how to log to multiple appenders:

• Log everything to a rolling log file
• Log errors to the Windows Event Log
• Send errors to an administrator via email

Sample Configuration:

<log4net>
  <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender" >
    <param name="File" value="C:\TEMP\fcfl.net.compat\fcflnet.log" />
    <param name="AppendToFile" value="true" />
    <param name="RollingStyle" value="Size" />
    <param name="MaxSizeRollBackups" value="100" />
    <param name="MaximumFileSize" value="1024KB" />
    <param name="StaticLogFileName" value="true" />
        
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [user: %X{user}] [fcsessionid: %X{session}] [%-5p] [%c]%n  %m%n%n" />
    </layout>
     
  </appender>
  
  <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
    <param name="ApplicationName" value="Dovetail Software" />
    <param name="Threshold" value="error"/>

    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [user: %X{user}] [fcsessionid: %X{session}] [%-5p] [%c]%n  %m%n%n" />
    </layout>
  </appender>
  
  <appender name="SMTPAppender" type="log4net.Appender.SMTPAppender">
    <param name="To" value="someone@company.com" />
    <param name="From" value="someone@company.com" />
    <param name="Subject" value="Message from First Choice Log Manager" />
    <param name="SMTPHost" value="smtp_server_name" />
    <param name="LocationInfo" value="false" />
    <param name="BufferSize" value="1" />
    <param name="Lossy" value="true" />

    <!-- only email out errors -->
    <evaluator type="log4net.spi.LevelEvaluator">
      <param name="Threshold" value="error"/>
    </evaluator>

    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [user: %X{user}] [fcsessionid: %X{session}] [%-5p] [%c]%n  %m%n%n" />
    </layout>
  </appender>
  
  <root>
    <level value="all" />    
    <appender-ref ref="RollingFileAppender" />
