[logback-user] Dynamically change a variable value for file location

[Douglas Moraes]

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
