Structure of the Logging Configuration File

The layout of a logging facility XML configuration file must contain, at minimum, the <?xml?> element, the <logging> element, and a <root> logger. The first two elements, in order, are these elements:

After the <logging: configuration> element, these elements can appear in any order:

See XML Elements for Configuring SAS Logging for information about the number of instances for each element.

Here is an example configuration file that shows the structure of the configuration file:

<?xml  version="1.0" encoding="UTF-8"?>
   <logging:configuration xmlns:logging="http//support.sas.com/xml/logging/1.0/">
      <appender class="RollingFileAppender" name="TimeBasedRollingFile">

         <param name="Unique" value="true"/>
         <filter class="StringMatchFilter">
            <param name="LevelToMatch" value="error"/>
            <param name="AcceptOnMatch" value="true"/>
         </filter >
         <rollingPolicy class="TimeBasedRollingPolicy">

         </rollingPolicy>
         <layout>
