Collecting data without SNMP-Interface

Hi folks,

I've a rather odd problem with a node. It has no IF-MIB, but has some 
metrics I want to collect. Node responds to snmwalk, but it gives only 
some very basic data, like sysObjectID, location, name, etc. But no 
interface-data whatsoever. Therefore the "SNMP-Interfaces"-tab on the 
node-page is plain empty, only the "IP-Interfaces" lists the address.
The metrics I want to collect are visible to snmpwalk, even ONMS 
gets/builds the table in the RRD-directory correctly, with 
strings.properties filled with the description of every element of the 
table, etc..Have full debugging on collectd, the node doesn't show up 
there...

I assume the reason why the collection doesn't work is because of the 
missing primary *and* secondary snmp-interface. Can anybody confirm this?

So, the question is, how to convince ONMS to collect data with a missing 
primary and secondary interface?


Complaining their broken SNMP-Agent to the vendor, and convince them to 
fix this, is not an option here....


My datacollection-config (tried to change the StorageFlag to "all", did 
not help):
(non-relevant parts deleted...)

     <snmp-collection name="CHRISTIE" snmpStorageFlag="all">
         <include-collection dataCollectionGroup="CDS-PJTR-CP2220"/>
     </snmp-collection>


datacollection-group:

<resourceType name="cdcp2220TempSensorsEntry" 
label="cdcp2220TempSensorsEntry" resourceLabel="${cdc2220TempSensDevi}
       <persistenceSelectorStrategy 
class="org.opennms.netmgt.collection.support.PersistAllSelectorStrategy"/>
       <storageStrategy 
class="org.opennms.netmgt.collection.support.IndexStorageStrategy"/>
    </resourceType>


<group name="cdcp2220TempSensorsTable" ifType="ignore">
     <mibObj oid=".1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.1" 
instance="cdcp2220TempSensorsEntry" alias="cdc2220TempSensInde" 
type="integer32"/>
     <mibObj oid=".1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.2" 
instance="cdcp2220TempSensorsEntry" alias="cdc2220TempSensDevi" 
type="string"/>
     <mibObj oid=".1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.3" 
instance="cdcp2220TempSensorsEntry" alias="cdc222TemSenDioErro" 
type="integer32"/>
     <mibObj oid=".1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.4" 
instance="cdcp2220TempSensorsEntry" alias="cdc222TemSenLowLimi" 
type="integer32"/>
     <mibObj oid=".1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.5" 
instance="cdcp2220TempSensorsEntry" alias="cdc222TemSenUppLimi" 
type="integer32"/>
     <mibObj oid=".1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.6" 
instance="cdcp2220TempSensorsEntry" alias="cdc2220TempSensValu" 
type="gauge32"/>
  </group>


sysObjectID matches the node:

     <systemDef name="Christie CP2220">
<sysoidMask>.1.3.6.1.4.1.25766.1.12.1.2.</sysoidMask>
       <collect>
<includeGroup>cdcp2220TempSensorsTable</includeGroup>
       </collect>
     </systemDef>


Result of snmpwalk:
snmpwalk -c public -v 2c w.x.y.z if
IF-MIB::ifTable = No Such Object available on this agent at this OID

Example walk of instance 10:
snmpwalk -c public -v 2c w.x.y.z 1.3.6.1.4.1.25766.1.12.1.2.2.2.1.1.6.10
SNMPv2-SMI::enterprises.25766.1.12.1.2.2.2.1.1.6.10 = Gauge32: 27
