I wrote a shell script to check my mikrotik devices for available updates. It works like a nagios plugin and can be well integrated in different monitoring solutions.
Exampleoutput: RouterOS version 6.38.3 is up to date (Release: Di 07 Feb 2017)
It works over SNMP or SSH and can also check a selected release tree.
More about it at my github:

Any suggestions?
