[logback-user] Why is RollingFileAppender so noisy?

[cowwoc]

Hi,

     I am trying to configure logback to launch silently (without 
outputting verbose information about its configuration).

     When my configuration file contains:

     <appender name="file" class="ch.qos.logback.core.FileAppender">
         <file>../../../foo.log</file>
         <append>false</append>
         <encoder>
             <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level 
%class{}.%method\(\) - %msg%n</pattern>
         </encoder>
     </appender>

I don't get any output at startup (good!). When I replace this with:

     <appender name="file" 
class="ch.qos.logback.core.rolling.RollingFileAppender">
         <file>../../../foo.log</file>
         <append>false</append>
         <rollingPolicy 
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>../../../foo.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
             <timeBasedFileNamingAndTriggeringPolicy 
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                 <maxFileSize>100MB</maxFileSize>
             </timeBasedFileNamingAndTriggeringPolicy>
         </rollingPolicy>
         <encoder>
             <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level 
%class{}.%method\(\) - %msg%n</pattern>
         </encoder>
     </appender>

I suddenly get this output:

     Any idea why RollingFileAppender is producing all this noise?
