Rotate Apache logs with Cronolog

Cronolog is log rotation program which gives you a lot of options to template the log destination files. The common use is to split logs by year / month / day.

Here is how to configure Apache to send log entries to cronolog :

CustomLog "|/usr/sbin/cronolog /home/log/apache2/%Y-%m-%d_domain.com_access.log" combined

This will create a log file named 2008-06-02_domain.com_access.log for today.

Cronolog reads log entries from standard input and writes them to the output file specified by your template.
