I've created a method to monitor that the tunnel is up and passing traffic using the ping subagent. Essentially, I ping the internal ip of the remote side from the clients server in our datacenter. I'd like to have a dashboard that has a nice green / red indicator based on whether the remote side is up (IE, if the ping is below 10000 which is the subagent timeout value then indicate green otherwise indicate red. )

Any ideas or suggestions?
