You can create an external monitor, that's a unix external script that is run by the OS and that returs an OK if it succeeds. The script would be configured to send one ping with a timeout of 1 second (ping -c1 -W1). You would have to catch the result of the ping, if it's OK then output something to the stdout, else output nothing.
