Hi Ron,

Did you check snmposter as described in the zenoss labs documentation? Perhaps this could be helpful: http://docs.zenosslabs.com/en/latest/zenpack_development/monitoring_snmp_device/snmp_tools.html

What I've done in this situation is to use a GUI MIB browser (I like the iReasoning one myself) to load the MIB and go through it looking for relevant or interesting MIBs.

Most Zenoss "components" you'll want to map to any SNMP tables within the MIB (w/the component and modeler code), while any top-level OID metrics you might want to stick on a Device template. 

Since you're working blindly though, several problems can occur:

1. The OID may (and likely does) contain many more entries than what the device will actually return
2. Sometimes the OIDs are written incorrectly, or the devices don't actually use the MIB correctly
3. Others I can't recall

Anyway that's about the best I can recommend.  Hope it helps.
