Hi

I use the snmp track to monitor active VPN tunnels whic works great. HOWEVER, if I add critical or warning I get the alarms for when things are byond the markers.
I need it to be if things go bad and the firewall drops the tunnel.

Is there any way to invert the critical and warning status.

Thanks
