Hello,
in a project i changed the rolling policy in the web-logback.xml from TimeBasedRollingPolicy to SizeAndTimeBasedRollingPolicy:
...
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>${logDir}/app.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<!-- each file should be at most 5MB, keep 30 days worth of history, but at most 2GB -->
<maxFileSize>5MB</maxFileSize>
<!-- keep 30 days' worth of history -->
<maxHistory>30</maxHistory>
<totalSizeCap>2GB</totalSizeCap>
<cleanHistoryOnStart>true</cleanHistoryOnStart>
</rollingPolicy>
...
Then I flooded the log file to see if a new log file is created from logback 5 MB. Unfortunately I had to find out that instead of the new log file the performance of the system dropped dramatically.
Does someone have the same problem and could solve it?
Here the whole war-lockback.xml:
