Plesk has a built-in mechanism that generates daily, weekly, or monthly reports on resource usage by customers, resellers, and domains. You can view these reports in Server Administration Panel > Tools & Settings > Summary Report.
There are two types of report:
- Summary reports contain common information, such as number of customers and resellers, total traffic and disk space usage, number of domains, subdomains, mailboxes, and so on.
- Full reports contain all the information from summary reports and separate statistics on resource usage for each customer, reseller, and domain.
To switch between summary and full reports, choose the corresponding value in the checkbox at the top left of the screen.
You can also make Plesk send these reports to a certain email address. To do so, go to Tools & Settings > Summary Report (under “Statistics”) > Delivery Schedule and choose the schedule from the existing ones or create a new one.
