Problem/Question
ethtool can read optic light levels off of newer NICs (using I2C), can this be added to netData to trend? The Tx/Rx light levels of each channel as well as warning/alarm status are what I’m interested in seeing. Other optics might report frequency, BER (bit-error-rate) and possibly SNR. I’ll see if I can dig up an example.
