Monitoring (Realtime Graphs, LEDs, Collectd) for LAN Interfaces Connected to Switch-chip

@dpdrown Thanks again for the suggestion to use ´ethtool´ . The adapted Lua script now works. :slight_smile: See LED color based on bandwidth usage for details.

Side note: ethtool -S creates different outputs depending on the interface. E.g. in_good_octets and out_octets do not exist for eth2. For eth2 those are called good_octets_received and good_octets_sent.

Any idea on the Realtime Graphs?
