PulseNET does not issue a heartbeat in the network. PN only broadcasts on the network to do a poll. The closest thing PN has to a heartbeat is an ICMP poll that determines reachability and is shown as Availability. However, something to note, in a SD only network, ICMP only gives you the availability to the Master.
