pppoe-charts

isd there any way to make charts graph data via a system idea

example

i have ip pool of 10.0.0.0/8 for pppoe-client connections

each connection has system id set example zw00001,zw00002 etc
but it can get any ip adress in th range 10.0.0.0/8

so i want to gragh data via the system id so the due will scan 10.0.0.0/8

so ti will pic up ip and cpu@zw00001 automatic so can i set it to graph pppoe data flow via the name?
