Logback, set max history files per day

Question

I use TimeBasedRollingPolicy and SizeAndTimeBasedFNATP triggering policy for my logback configuration. The rollover of log files is set to happen every day and it will also be triggered if log file size goes beyond a limit.

If I do setMaxHistory(10) on TimeBasedRollingPolicy with a daily roll over, then it will archive all log files in last 10 days. But what I want is to set maxHIstory on SizeAndTimeBasedFNATP each day.

Is this possible with logback?

Solution

With SizeAndTimeBasedFNATP and MaxHistory set to 10, the logs older than 10 days will be removed (assuming daily rollover schedule). Size is not factored in the into removal logic.
