Apparently DNSSD is not working for me. I don't have access to the DNS server so my guess is the #4 below is not set properly. I turned off DNSSD and instead manually added a collector which pointed to my Ganglia server running the enabled gmond. After restarting hsflowd, I started to see packets showing up on the gmond server. After fixing another gmetad configuration problem, my box running sflow showed up. Very cool.
