Just found out about GetIf, free SNMP tool for windows. If you are exploring SNMP on MikroTik this may be valuable stuff. It allows you to freely explore MIBS/OID’s, and also can show graph for selected OID’s. As novice, I found it very helpful to understand using SNMP on Mikrotik.

I hope someone would make MIB definition for this application and make it even more usable.
