Hello, I am able to use the FixedWindowRollingPolicy along with SizeBasedTriggeringPolicy to achieve roll over based on defined file size (logback-1.2.3) . However I need to change the name of the file on roll-over such that instead of the index the current date and time would be used in the rolled over file name. For example: if the current file name is abcApp.log, the rolled over file name should be abcApp_2019-08-20_203522.log (The roll0over would happen when the defined file size is reached based on the defined SizeBasedTriggeringPolicy) Is there any way in existing rolling Policy classes that support this? I couldn't find any. Or any other way to achieve this? If there is no support for this, I would be willing to add support by either tweaking the existing FixedWindowRollingPolicy class or creating a similar new class and supplying the same. Please let me know. Thanks & Regards, Deepak.
