[Observium] eth0, vlan, missing port speeds

Hi All,

this is a random question,

I’ve just noticed on my Observium that the is no Port speeds for any of our Ethernet ports on our debian servers ?

but also, the is no Ports speeds for any of our VLAN interfaces on our mikrotik switches either ?

I don’t have any event-logs showing the speeds changed or anything?

where should i begin looking why the speeds have just vanished?

Regards

Simon
