Traffic sum of discovered interfaces

[gattomark]

Hi,

I have created "Template" with inside a "Discovery rule" SNMPv2 based on "IF-MIB::ifAlias" to create ifInOctets and ifOutOctets items of all interfaces that I need to monitor.

Now I need to create a graph and a trigger based on the sum of all ifInOctets and the sum of all ifOutOctets of these interfaces. How can I do?

(sorry my english)

Thanks,
Marco

Do you have any solution?

The only way to do this is knowing all your item names and create a calculated item writing a big expression.

If your device do not have a specific SNMP item to get total traffic, you could write um script to sum all interface traffic and use "external script" item type.

Otherwise, depending of your intention, you can only monitor the interface of external traffic.

Any news in version 3.0, for not create a script?
Thanks
