Add graph(s) that represent currents transfer speeds for all available network interface(cards).

[NemoDima]

Could you add graph(s) that represent currents data transfer speeds for all available network interface(cards)?

We use dedicated servers(win 2016) with few ethernet cards, which connected to the internet and vlan respectively.
Sometimes, our hosting company have problem with their network infrastructure and we want know about it immediately.

Maybe you can use this counters
Network Interface\Bytes Total/sec
Network Interface\Bytes Received/sec
Network Interface\Bytes Sent/sec
perf_counter[\Network Interface(*)\ ...]
or
net.if.in, net.if.out, net.if.total and net.if.discovery

I hope that its can help you:

https://support.zabbix.com/browse/ZBXNEXT-2765

I would be very grateful if you can release such graph(s).
Thanks a lot.

Feel free to send PR against devel branch :)
