Calculating the sum of the network bandwidth

[karzer]

Hi;
I want to learn; how to calculate the sum of the network bandwidth consuption.

I can get the values from Discovery Template:

1)Incoming network traffic on {#IFNAME}
2)Outgoing network traffic on {#IFNAME}

For example; I want to get the result values of consumtion for 12 hours' part.

In this case; if you help me for this situation, I will be appreciated.

Thanks.

I also want to do this for my huawei NE40E-X3 The only workaround I can imagine is to create an item per interface name and a calculated item that will sum them.

Something like:
eth0_aggregate : grpsum["MyHostGroup","net.if.in[eth0,bytes]","last","0"]
eth1_aggregate : grpsum["MyHostGroup","net.if.in[eth1,bytes]","last","0"]
bond0_aggregate : grpsum["MyHostGroup","net.if.in[bond0,bytes]","last","0"]
