[logback-user] Help with logback configuration

4 Feb 2011

      Thanks for your help...I just switched from log4j to slf4j/logback and this
is one issue holding us up from moving to QA/UAT...so I am on a fire drill.

If what I have here is not the right way to think about logging for my
scenario...please let me know.

I have multiple variations I have tried, but I will list the two here.

WLS 11g, in my war [SLF4J 1.6.1 api/ext, Logback 0.9.27 core/classic,
log4j-over-slf4j 1.6.1, jcl-over-slf4j 1.6.1]

I have multiple wars that run in 1+ managed instances of WLS that write to
the same central log files.  Trying to have one central log and each
application have their individual log files (but one across the managed
instances...unless it's easier for each managed instance to have its own
copy).

1) I included slf4j/logback jars in WLS lib directory and add one
logback.xml file into the main/resources directory so when the war is built
it gets put into WEB-INF/classes of the war.
- No log files are produced at all, not even writing a 0 byte file.
2) I included slf4j/logback in a preclasspath folder that I add into WLS
startup scripts and I also added
-Dlogback.configurationFile=%DOMAIN_HOME%\lib\logback.xml into the startup
script.  I excluded a configuration file from the war.  
- Log files are created, but nothing is printed to any of the log files.

Here is my config:
<configuration>

  <appender name="sc-resources.log"
class="ch.qos.logback.core.rolling.RollingFileAppender">
    <prudent>true</prudent> 
    <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!-- daily rollover -->

<fileNamePattern>./logs/sc-resources.%d{yyyy-MM-dd}.log</fileNamePattern>

      <!-- keep 30 days worth of history -->
      <maxHistory>30</maxHistory> 
    </rollingPolicy>
    <encoder>
      <pattern>%d [%thread] %level %logger - %m%n</pattern>
    </encoder>
  </appender>

  <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d [%thread] %level %logger - %m%n</pattern>
    </encoder>
  </appender>

  <logger name="com.foo.service.mem" level="trace">
    <appender-ref ref="MemberSearchBusinessService" />
  </logger>

  <appender name="MemberBusinessService"
class="ch.qos.logback.core.rolling.RollingFileAppender">
    <prudent>true</prudent>
    <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!-- daily rollover -->

<fileNamePattern>./logs/MemberBusinessService%d{yyyy-MM-dd}.log</fileNamePattern>

      <!-- keep 30 days worth of history -->
      <maxHistory>30</maxHistory> 
    </rollingPolicy>
    <encoder>
      <pattern>%d [%thread] %level %logger - %m%n</pattern>
    </encoder>
  </appender>

  <logger name="com.foo.service.mem" level="trace">
    <appender-ref ref="MemberBusinessService" />
  </logger>

  <logger name="org.apache.cxf" level="debug">
    <appender-ref ref="sc-resources.log" />
  </logger>

  <logger name="org.hibernate" level="warn">
    <appender-ref ref="sc-resources.log" />
  </logger>

  <logger name="org.quartz" level="warn">
    <appender-ref ref="sc-resources.log" />
  </logger>

  <logger name="org.springframework" level="warn">
    <appender-ref ref="sc-resources.log" />
  </logger>

  <root level="trace">
    <appender-ref ref="stdout" />
    <appender-ref ref="sc-resources.log"/>
  </root>
</configuration>

Thanks for your help....jay
