Hello,
I Have IPv6 traffic on Mikrotik CCR-1036, But Mikrotik unable to send IPv6 traffic related data on SNMP to Observium. In cisco we are getting the IPv6 traffic data to OBS.
You'll have to describe what exactly you deem wrong at Mikrotik side.
Instead of writing novels, post /export hide-sensitive. Use find&replace in your favourite text editor to systematically replace all occurrences of each public IP address potentially identifying you by a distinctive pattern such as my.public.ip.1.
