The Customer Usage report displays network usage on a per customer basis. Customer names are parsed from the interface comments in the imported configuration files. The regular expression used to parse the customer names can be customized by selecting a device from the Hardware Inventory window, going to the Logical View panel, selecting Actions > Options, and going to the Misc tab. There, you will see a section called Customer Identifier with a field called Use regular-expression in interface description. Enter your custom regular expression here.
The parser looks for customer names within parenthesis. For
example, to match a number sequence in interface comments of the format,
cust####..., use the expression,
cust([0-9]+).* There is currently no way to define customers other than parsing
them from interface comments in the imported configuration files.
