Create a new log file, each run in a log?
How do I create a new log file every time I start the application?
I would like to keep the previous logs. For example, I would prefer to name each new log file by its creation time and date. Otherwise, I agree to archive the old log file at the date and time of the file name.
Unfortunately I don't see any relevant policies and / or triggers here: http://logback.qos.ch/manual/appenders.html
UPDATE
I did something like "duplicate"
<appender name="ROUTINEAPPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>logs/routine.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>logs/routine%d{yyyyMMdd}%d{HHmmss,aux}.log</fileNamePattern>
<TimeBasedFileNamingAndTriggeringPolicy class="com.inthemoon.toolkit.StartupTimeBasedTriggeringPolicy" />
</rollingPolicy>
<encoder>
<pattern>%d{HH:mm:ss.SSS} - %C{0} - %msg%n</pattern>
</encoder>
</appender>
but my class is com.inthemoon.toolkit.StartupTimeBasedTriggeringPolicy
never called. I put a breakpoint in the method start()
, but it never went up.
There is also no swing. The log file is created but always has a name routine.log
.
Also I don't understand how the file
and parameters coexist filenamePattern
.
UPDATE 2
I have the class reference fixed UPDATE 1
, but I don't have what I need yet. In this solution, the date time is inserted in the name of the log OLD file. For example, if I ran the program in 2013, it created routine.log
. Then I waited a year and launched the program in 2014. A new log file will be created and will have a name routine.log
, and the OLD 2013 log will be placed in routine2014XXXXXXXXXX.log
, which is absolutely irrelevant.
I need to create a new file every time I run the program and have this file tagged with a date and time stamp.

The following configuration will create a new log file and console output every time you run the program, please note that it does not use RollingFileAppender. For more information see the protocol documentation https://logback.qos.ch/manual/configuration.html
<configuration>
<timestamp key="bySecond" datePattern="yyyyMMdd'T'HHmmss"/>
