Subject RE: How to config log4cxx to delete the log files periodically

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.
