C.3. Redirecting Category Output
When you increase the level of logging for one or more categories, it is often useful to redirect the output to a separate file for easier investigation. To do this you add an
appender-ref
to the category.
Example C.4. Adding an appender-ref
<appender name="JSR77" class="org.apache.log4j.FileAppender"> <param name="File" value="${jboss.server.home.dir}/log/jsr77.log"/> ... </appender> <!-- Limit the JSR77 categories --> <category name="org.jboss.management" additivity="false"> <priority value="DEBUG"></priority> <appender-ref ref="JSR77"></appender-ref> </category>
All
org.jboss.management
output goes to the jsr77.log
file. The additivity
attribute controls whether output continues to go to the root category appender. If false
, output only goes to the appenders referred to by the category.
