[Observium] Problem with MIBs

Hello;

I recently have installed the Community version of Observium on a CentOS 7 server, to test the functionalities and the configurations that gives; to decide if I it's worth to purchase for the Professional one.

My question is about how can I select wich MIBs is going to use to obtain data. Because when I go to Devices -> Select Device -> Properties -> MIBs I find a list of MIBs that are used but not suitable for my device. How can I change it?

Entering through the server's folders I have seen that are the MIBs that I need. How can I run it to get the appropiate data?

Thanks!
