RollingFileAppender - rolling yearly?

Question

Is it possible to set the RollingFileAppender to roll yearly rather than monthly? There won't be enough entries to require one file per month, so I'd like to set it up on a yearly basis, but when I set the datePattern = "yyyy" log4net said it was unable to parse (Invalid Roll Point).

Answer 1

No.

RollingFileAppender.RollPoint.TopOfMonth is the biggest value.

See http://logging.apache.org/log4net/release/sdk/log4net.Appender.RollingFileAppender.RollPoint.html for reference.
