Monitor multiple ports traffic

[Luiz Barreto]

Hello,

I have a network and I need to do traffic reports every month. I need to measure how much bytes passed by the switch port in a specific period of time. The Zabbix has a report option to this: "Bar reports" and "Distribution of values for multiple periods".

My real problem starts now. I need a report of a sum of several ports in a few hosts. The ports are not the same one in every host. I need, for example, a report of the sum of:

Switch1: ports 1, 3 and 5;
Switch2: port 20 and 21;
Switch3: port 2;

Before the usual answers, I can't use the option "Zabbix aggregate cause the ports aren't the same on the hosts.

Please, can any one help me?

Thank's
