Hi Douglas,
The <file> property is optional RollingFileAppender. Without it,
RollingFileAppender will behave in the way you want.
Try the following:
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy
  class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <fileNamePattern./log/%d{MMdd}/gp2b.log</fileNamePattern>
    <maxHistory>30</maxHistory>
 </rollingPolicy>
 <encoder>
    <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36}:%L -
%msg%rEx{10}%n</pattern>
 </encoder>
</appender>
Let us know how it goes.

Hi,
I want to save my log file in a directory accordingly the current day.
For example, if today is 0614 (June 14th), all log events will go to a
folder 0614, and tomorrow I want the logs to go to 0615.
I don´t want use rolling policy. I mean, I want the file to be directly
created in the right place, and not saved in a temporary place and in
other day to be saved in an archive place.
I tryed:
<configuration>
    <timestamp key="DIR" datePattern="MMdd" />
    <appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>./log/${DIR}/gp2b.log</file>
        <rollingPolicy
class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>app.%i.log</fileNamePattern>
            <minIndex>1</minIndex>
            <maxIndex>10</maxIndex>
        </rollingPolicy>
        <triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>5MB</maxFileSize>
        </triggeringPolicy>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36}:%L
- %msg%rEx{10}%n</pattern>
        </encoder>
    </appender>
<logger name="com.ocs.ProxyHttp.gp2b" level="DEBUG" />
<root level="DEBUG">
        <appender-ref ref="FILE" />
    </root>
</configuration>
Thanks,
Douglas
