There is an Mikrotik template. I'm checking: traffic on all ports, cpu load, cpu temp, motherboard temp, memory load. It uses 1 discovery (for ifaces), and 50 items (in initial release, 36 CPUs :)) and 42 static triggers
Each discovery goes to fill 6 items (port status, port admin status, bytes in, bytes out, pps in, pps out), taking via OID (no need to get mib)
Template builded to monitor an Mikrotik CCR1036-8G-2S+, but should fit any other.
For import you need to add regex
Name: Mikrotik interfaces Expression: .*slave.* Result: Result is FALSE
