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

and few value mappings

Host Status 2.0	
0 ⇒ Unreachable
1 ⇒ UP

Network port admin status	
1 ⇒ Enabled
2 ⇒ Disabled

Network port status	
1 ⇒ Up
2 ⇒ Down
