- Bibliomancy
- Other ?
Jokes aside, you posted ~1230 times on this forum, how comes you still don't know how to efficiently write a question ?
You write about grafana, but are not explaining why, you're not explaining the context, you're not explaining what you're doing, what you tried and is working, what is exactly blocking you, you're not specific, you're asking if there is an issue with your configuration, but which one(s) ? you're not even sharing any configuration... We don't even know if / how it is related to Mikrotik... How are we supposed to help in this context ?
The only answer I can give you is : yes you have a configuration issue *somewhere* (otherwise it would work flawlessly). But I doubt it helps...
