I want to know if it is possible to change the collor to yellow if the TTL reach a certain value? I am using bigbrother on an windows environment.

For example I want to know when a router (which I haven't under controle) switch over to the backup line. For me the only messurement is the TTL time which will increase.

I want to change the status to yellow and when the connection not is availble to red. Do someone have a solution for this?
