a quick search brought only this result:

 octo at huhu:~ $ egrep -r '\<128\>' /usr/include/net-snmp | grep ASN
 /usr/include/net-snmp/library/snmp.h:#define SNMP_NOSUCHOBJECT (ASN_CONTEXT | ASN_PRIMITIVE | 0x0) /* 80=128 */

So it seems like that device simply can't return one of the OIDs you
have configone of the OIDs you have configured.

Have you tried running `snmpwalk' manually to check if any reasonable
values are returned at all? Also, are any files created at all? I. e.
does `not seeing any stats' mean that the files are missing or that they
are empty (or rather, filled with NaNs)?
