The 1500 bits are for each ping. So 1000 hosts would be 1,500,000 bits per ping cycle at the monitor server, but not on each leaf router. The designer would need to analyze the network topology to see if there are any possible choke points. In a cable internet system, 1000 customers on a single up/down channel pair would require 700 kilobits each way per ping cycle. Yes, this is payload bandwidth, it doesn't include packet overhead.
