Log rollover: activate based on size but keep "creation date" in file name?
Hello, I'm trying to configure a naming scheme that would result in longs in the format of %d{yyyy-MM-dd-HHmm}.%i.log, however the time should indicate log creation time, not current time. New log is created in 2 situations: on application launch <rolloverOnStart>true</rolloverOnStart> or <maxFileSize>1MB</maxFileSize>. However, because of the naming format, the log gets put in a different location every minute. Is there a way to only set the log name on creation and then write to it until next rollover? Thank you
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].

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? ________________________________ From: ceki <ceki@qos.ch> To: logback users list <logback-user@qos.ch> Sent: Friday, June 8, 2012 3:57:11 PM Subject: Re: [logback-user] Log rollover: activate based on size but keep "creation date" in file name?
