SNMP Configuration for mikrotik routers
Configuration on mikrotik
IP --> SNMP --> Communities
Create community simmy with high encryption
Enable and select the trap community
Configuration on checkmk
I created a folder for all mikrotik devices.
Use the same community and passwords as above!
For the network scan I limited the IP-Range to the range where all mikrotik devices have their IP address.
On most of the devices I disabled the "Filesystem system disk" check, hence it would always trigger an alarm on the mikrotik defaults.
