[logback-user] Log rollover: activate based on size but keep "creation date" in file name?

[Yura Levandovskyy]

Thank you for the suggestion

I've tried it, and it seems to set the aux part on application launch, but not on new log creation. So, specifically, right now I get:

2012-06-11.1201.1.log (creation time 12:01, application launched)
2012-06-11.1201.2.log (creation time e.g. 12:05, rollover due to size)
2012-06-11.1201.3.log (creation time e.g. 12:10, rollover due to size)


What I'm trying to achieve is the following:

2012-06-11.1201.1.log (creation time 12:01, application launched)
2012-06-11.1205.2.log (creation time e.g. 12:05, rollover due to size)
2012-06-11.1210.3.log (creation time e.g. 12:10, rollover due to size)

The rollover, according to policies in effect, occurs on log size or every day. 
What could be the issue here?

Hi Yura,

Have you tried auxiliary timestamps in fileNamePattern? For example,

   %d{yyyy-MM-dd}-%d{HHmm,aux}.%{i},log

The primary date token, %d{yyyy-MM-dd}, determines roll over period,
i.e. 24 hours, where the auxiliary pattern, %d{HHmm,aux} contributes
to the file name of the archived log files.

For more details, refer to docs on TimeBasedRollingPolicy's
fileNamePattern [1].

HTH,
