It sounds like you are on the right track, but here is a little hsflowd troubleshooting checklist...
On the source (box running hsflowd): (1). Any error messages in /var/log/messages? (2). Check /etc/hsflowd.conf, is the collector set, or is DNSSD=on? (3). If using DNSSD, is the "search" setting correct in /etc/resolv.conf? (4). If using DNSSD, are the SRV and TXT records in the zone file on the DNS server? (5). You can run hsflowd at the shell prompt with debug logging: "root> hsflowd -dd" On the destination (box running gmond): (6). sFlow enabled in gmond.conf? (7). check firewall settings (e.g. "root> iptables --list") (8). Watch for an sFlow packet arriving every 20 seconds or so: "root> /usr/sbin/tcpdump -n udp port 6343" (Just remember that tcpdump sees packets before they hit the firewall, so check (7) may still apply) On the UI: Should look exactly the same as is if gmond were running on the source too.
