Custom certification shows no data for all metrics in DX Performance Management.
Looking at detailed poll logging in dcdebug, the response after delta processing shows values, but response after data processing shows all NULL values.
When looking at the SNMP response for the scalar OIDS, the requests are being sent with .0 but the responses do not have a .0 appended to them.
Release : 3.7
Component : IM Reporting / Admin / Configuration
This is not a correct response and causes the OID mapping to fail.
If the device supports requesting the scalar OIDs without a .0 then you may be able to use that instead.
Otherwise, the MIB would need to respond correctly
