That is already possible. You would need to use the RollingFileAppender that is 
in the rolling namespace. It is a more flexible class and is the superclass 
that the others are derived from. With it you specify a rolling policy and a 
triggering policy (the time based one is both). You could easily subclass the 
time based triggering policy to do whatever you want. Note that this only works 
with an XML configuration file. The more general rolling.RollingFileAppender 
cannot be configured using a properties file.

I suppose that if it were possible to define a callback that would be invoked 
when a roll-over takes place it would be possible to do the kind of 
housekeeping he wants without needing to use the crontab…

Log4Cxx does not have this capability. It only lets you specify a max number of 
files when using the size based rolling policy. This is not an arbitrary 
decision. There is no good way to accomplish what you want. How is log4cxx 
supposed to know what files it can delete? Log4cxx maintains no history of what 
files it has created in the past.

 I suggest you create a daily job that deletes log files that are more than 31 
days old based on creation date.
