[mysar-support] No data in MySQL database

[Andrew H. <and...@gm...>]

I have successfully installed mysar.  The web page loads but there is no
usage data in it.  I then logged into my MySQL database, and the tables are
all empty, except for the Configuration table.

Is there something I must do before mysar imports data from squid?  I have
heard some people on the forum mention cron.  I don't know anything about
cron? Do I need to do something with it before mysar will work?

Please help.  I would love to get mysar to work, especially since I am
learning to use PHP as well.

Thanks.
