Subject RE: How to config log4cxx to delete the log files periodically
Date Tue, 16 Sep 2008 18:06:12 GMT
From what I've seen out there... small biz to large enterprises is that 
for System Admins, they see deleting logfiles as part of a global task 
that they generally set-up as part most large-scale enterprise systems. 
They prefer to have one point that manages all historical data, archiving, 
etc. and do not really appreciate when a process deletes its logfiles. 
Specifically, we have customers who maintain logs for 3 days and some even 
up to 30 days, and some that archive old logs for compliance/audit 

So... while I agree that a listener interface that one can register for 
log rotation would be nice, IMHO most large-scale uses of Log4CXX would 
not be able to use that to delete log file...

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

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.
