(1) Yes - Networks Flows is useless - it records the # of packets ntop
routes into a plugin. Since the plugin listens for sFlow itself, zero is
normal.
(2) From the code, it doesn't look like sFlowPlugin does anything special
with VLANs:
/*_________________---------------------------__________________
_________________ readCounters_vlan __________________
-----------------___________________________------------------
*/
static void readCounters_vlan(SFSample *sample, int deviceId)
{
sample->in_vlan = getData32(sample, deviceId);
if(SFLOW_DEBUG(deviceId)) traceEvent(CONST_TRACE_INFO, "in_vlan %lu\n",
sample->in_vlan);
sf_log_next64(sample, "octets", deviceId);
sf_log_next32(sample, "ucastPkts", deviceId);
sf_log_next32(sample, "multicastPkts", deviceId);
sf_log_next32(sample, "broadcastPkts", deviceId);
sf_log_next32(sample, "discards", deviceId);
}
Contrasting with this:
/* the generic counters always come first */
ifName.ifInOctets = sf_log_next64(sample, "ifInOctets", deviceId);
It looks like it's not doing anything with these counts.
You probably need to contact InMon directly, although I haven't seen any
signs of support for sFlowPlugin from them recently.

please... Somebody looking in the list for an sFlow problem in the future
won't think your question applies.

Subject: [Ntop] HP2848 VLAN Info
Hi guys,
I monitoring a HP Procurve 2848 with ntop v.3.1 (Dag Apt RPM Repository),
sFlow plugin 2.99.
First I activate sFlow data output to ntop machine with this instructions
(http://tinyurl.com/8l3nd), than I see, under Admin -> Plugin -> sFlow sFlow
Statistics, without packet with bad version or flows with bad date (I
suppose that sFlow traffic is valid for ntop).
Two strange things:
- Summary -> Networks Flows returns 0 packets and 0 traffic for sFlow... Is
it normal?
- Summary -> VLAN Info returns "No entries to display(yet)"...
Actually there are 10 VLANs that work correcly: how I can see statistics
about them?
Thank you,
fRANz
