Quering temp and power consumption using snmp

Hello, I have an Oracle M8 SPARC and I'm trying to get temp and power consumption using snmpwalk or snmpget commands from a Solaris server.

I already configured in the ilom cli under /SP/services/snmp/users/<user> an user account, pass, protocol and auth.

The snmpwalk works fine and bring me a list of entries, but I noticed that most of the values, the actual telemetry values, are empty.

Can you give me a hint about what I'm missing here?

As reference this is an example of what I get:

SNMPv2-SMI::mib-2.47.1.1.1.1.2.4202 = STRING: "Power Unit"
SNMPv2-SMI::mib-2.47.1.1.1.1.3.4202 = OID: SNMPv2-SMI::zeroDotZero
