I just found those fantastic statistic tools AWstats and Webalizer. Really great.
I log in to the stat tool with my ftp username, but I wonder how can I let my clients access the statistic with an other login? Those clients that I have choosed to put in my service account don?t need to know my ftp username and password. I would rather have a separate login for the statistic for each domain.
IF you are hosting many client websities inside a single account then you need to send a ticket to support with the site details such as wesite name and corresponding user name. And they will create subftp accounts for the respective domains and grant then the right to view their Awstats and Webalizer.
