Single App needs two appenders with two sets of rights question

["McAninch, Robin" <RM...@russellmellon.com>]

Hi

I have a requirement to write to a log file for all normal logging actions using the rolling file appender attached to the root or some other logger level.  I additionally need to send an email to a given address if a fatal or Error message occurs.  Both appenders work by themselves or attached to a logger at the same level but that is the problem.  I need global coverage for both but only want to write emails for the serious errors.  How can I configure my file to allow me debug level for writing to the logfile and fatal level sending of emails while covering the entire app.  Right now I either accept the same level for both or the more restrictive level supercedes the more general one.

<root>
	<level value="Debug" />
		<appender-ref ref="rollingFile" />
		<appender-ref ref="email" />
	</root>
	
	<!-- Define some output appenders -->
	<appender name="rollingFile" type="log4net.Appender.RollingFileAppender,log4net">
		<param name="File" value="MyFile.Business.Test.log" />
		<param name="AppendToFile" value="true" />
		<param name="RollingStyle" value="Date" />
		<param name="DatePattern" value="yyyy.MM.dd" />
		<param name="StaticLogFileName" value="true" />
		<layout type="log4net.Layout.PatternLayout,log4net">
			<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n" />
		</layout>
	</appender>
	
	<!-- Define some output appenders -->
	<appender name="email" type="log4net.Appender.SmtpAppender,log4net">
		<param name="From" value="Alert" />
		<!--
		<param name="Username" value="[optional user name]" />
		<param name="Password" value="[optional password]" />
		-->
		<param name="To" value="user@mysite.com"/>
		<param name="Subject" value="Fatal Error in program."/>
		<layout type="log4net.Layout.PatternLayout,log4net">
			<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n" />
		</layout>
		
	</appender>


Thanks,

You could put a filter on the email appender:

http://logging.apache.org/log4net/release/manual/configuration.html#filters

<appender name="email" type="log4net.Appender.SmtpAppender">
 <filter type="log4net.Filter.LevelRangeFilter">
  <levelMin value="ERROR" />
  <levelMax value="FATAL" />
 </filter>
 ...
</appender>
