You have already run cron-pages.pl and the output is the way you like.
It's time now to see how to launch the scripts every night.
Hourly or daily crontab use
If you want to have stats updated every hour, you'll need to launch your
crontab hourly. If you decide to run your hourly stats only once a day
(midnight is best), then your crontab need to be run only once
a day.
Multiple web server
If you need to run stats over multiple servers, don't run everything at the
same time ! For example, run the first scheduler for your first webserver
at 00 h 10, the second ten minutes later and so on.
