Usually log rotator logic will overwrite old logs with new ones, and you don't have this problem. Why is that not
workingfor you?

That question is up to you to answer. How far back do you want to be able to look? What do you do with your log files?
Asyou no doubt have realized, more logs take more space and so you can't just keep everything, but generally the more
thebetter. As a data point that may or may not be good advice for you, we keep a week's worth of log files, but mostly
that'sjust for paranoia. We do all our processing in real-time or the day after.
