@Alco what do want to monitor exactly? The Interface as such or somthing else? If you only want to monitor the interface i guess you need to change/create a interface discovery rule and add “131 - tunnel” to the discovered interface types.

One thing about the cisco_vpn_tunnel, this is still for pre CMK 2.0 versions and not yet testet with version 2.0.

Thanks, Yes I want to monitor the status if it is up or down

ext>sh ip int brief tunnel 1
Interface                  IP-Address      OK? Method Status                Protocol
Tunnel1                    172.16.1.1      YES manual up                    up 

Yes that was it, after enabling this rule all the interfaces became visible
