As a follow on...

using tcpdump and snmpget against the data in the dump shows the counters ARE being retrieved, just not registering.

snmpget -v 2c -c community666name 127.0.0.1 .1.3.6.1.2.1.31.1.1.1.3.4 -Oa

IF-MIB::ifInBroadcastPkts.4 = Counter32: 0

tcpdump was run while hand running xymoln-snmpcollect

OK, I have bug on this now... I have had off an on for a while now

I have one host in my network NOT being monitored by devmon and I'm trying to use the built in snmp of xymon

snmphosts.cfg:

I get the interface names, but no counters and as a result no RRD entries,and of course, no charting.

What I want it to do is collect the stats for all of the interfaces and then chart them.  I'm suspecting the ifmib definition isn't right if not that, the maybe I need to do 
something different with snmphosts.cfg

Thoughts?
