[users@httpd] Re: Log File Rotation Script

[Hugh Williams <hu...@soco.agilent.com>]

Hi;

I've found cronolog to be quite happy to rotate log files with date
strings in them - it's even mentioned in the Apache documentation.  I
crate daily log files and store them in monthly directories.

http://www.cronolog.org/

This will take care of the first part of your request.  The compression
bit is a matter of you running a monthly cron job to to the gzip; this
is on the cronolog "wish list" but is not part of the tool at the
moment.
