I don't believe so, no ... the network stack is implemented in VxWorks, and
is somewhat brittle in nature. The UI it presents only allows setting a
default gateway, although oddly enough the way this information is entered,
it gives the appearance that the default gateway applies only to the
management interface, not the data interface.

What seems to happen is OpenNMS eventually concludes that the management
interface is actually associated with the node for the data interface, and
treats it as a part of the data interface node, rather than as a separate
node. I'm not sure if this is by design or a side-effect, but if it's by
design, I think it's a good design, so cheers on that. :-)

Okay, that makes sense. I have a couple of disparate systems that also use a
sysObjectID of .0.0 -- there's an Apple XRAID enclosure that's similarly
brain-dead. I added this to the systems section of datacollection-config.xml
and re-scanned, but then the node stopped showing the 'Update SNMP' link
altogether so I'm still confused:
-- cut --
<systemDef name="Broken SNMP Implementations">
<sysoid>.0.0</sysoid>
<collect>
<includeGroup>mib2-host-resources-system</includeGroup>
<includeGroup>mib2-host-resources-memory</includeGroup>
<includeGroup>mib2-host-resources-storage</includeGroup>
<includeGroup>net-snmp-disk</includeGroup>
<includeGroup>net-snmp-proc</includeGroup>
<includeGroup>ucd-loadavg</includeGroup>
<includeGroup>ucd-memory</includeGroup>
<includeGroup>ucd-sysstat</includeGroup>
<includeGroup>ucd-sysstat-raw</includeGroup>
<includeGroup>ucd-sysstat-raw-more</includeGroup>
</collect>
</systemDef>
-- cut --
Additionally, I now see this message in the collectd.log (sorry for the
crappy linewrap):
-- cut --

-- cut --
10.99.42.93 is the IP address of the data interface, i.e., the one that
answers SNMP queries -- should I change the way the systemDef is matched or
should using '<sysoid>.0.0</sysoid>' match these broken implementations that
don't properly assign an enterprise OID number to the sysObjectID? Is more
information needed in datacollection-config.xml to get OpenNMS to gather
SNMP data from these nodes?
thanks,
Klaus
