Get Units From snmp OID

[Mate1213]

Hi!

I want to monitor all sorts of sensors in my devices. But in the SNMP walk these comes in a mixed version (not the same in all decvices) example:
.1.3.6.1.4.1.14988.1.1.3.100.1.2.14 = STRING: "temperature"
.1.3.6.1.4.1.14988.1.1.3.100.1.2.16 = STRING: "power-consumption"
.1.3.6.1.4.1.14988.1.1.3.100.1.2.17 = STRING: "cpu-temperature"
.1.3.6.1.4.1.14988.1.1.3.100.1.2.7001 = STRING: "fan1-speed"
.1.3.6.1.4.1.14988.1.1.3.100.1.2.7302 = STRING: "psu2-current"
.1.3.6.1.4.1.14988.1.1.3.100.1.3.14 = Gauge32: 68
.1.3.6.1.4.1.14988.1.1.3.100.1.3.16 = Gauge32: 290
.1.3.6.1.4.1.14988.1.1.3.100.1.3.17 = Gauge32: 54
.1.3.6.1.4.1.14988.1.1.3.100.1.3.7001 = Gauge32: 2085
.1.3.6.1.4.1.14988.1.1.3.100.1.3.7302 = Gauge32: 5
.1.3.6.1.4.1.14988.1.1.3.100.1.4.14 = INTEGER: 1
.1.3.6.1.4.1.14988.1.1.3.100.1.4.16 = INTEGER: 5
.1.3.6.1.4.1.14988.1.1.3.100.1.4.17 = INTEGER: 1
.1.3.6.1.4.1.14988.1.1.3.100.1.4.7001 = INTEGER: 2
.1.3.6.1.4.1.14988.1.1.3.100.1.4.7302 = INTEGER: 4

I'm confused the .1.3.6.1.4.1.14988.1.1.3.100.* OID because this is an matrix, where the .1.3.6.1.4.1.14988.1.1.3.100.1.4.* store the Unit.

Is there any way, to use value mapping for the units in discovery rules?
MIB:
mtxrGaugeUnit OBJECT-TYPE
SYNTAX INTEGER {
celsius(1),
rpm(2),
dV(3),
dA(4),
dW(5),
status(6)
}


Thanks for any Idea, or documentation (I didn't found any of this yet).
Best Regards,
Mate
