Hi Dave,
Thanks for the reply. I agree with what you are saying but there is a slight difference in Gauge32 and Unsigned32, which was misleading at least to me.
RFC 1155
3.2.3.3. Counter
This application-wide type represents a non-negative integer which
monotonically increases until it reaches a maximum value, when it
wraps around and starts increasing again from zero. This memo
specifies a maximum value of 2^32-1 (4294967295 decimal) for
counters.

counters.
3.2.3.4. Gauge
This application-wide type represents a non-negative integer, which
may increase or decrease, but which latches at a maximum value. This
memo specifies a maximum value of 2^32-1 (4294967295 decimal) for
gauges

Thanks again.

Because the two types are exactly the same thing.
>From RFC 2578 (defining SMIv2):
Gauge32 ::=
[APPLICATION 2]
IMPLICIT INTEGER (0..4294967295)
-- an unsigned 32-bit quantity
-- indistinguishable from Gauge32 <======
Unsigned32 ::=
[APPLICATION 2]
IMPLICIT INTEGER (0..4294967295)
We could switch to reporting everything as
Unsigned32 rather than Gauge32, I suppose.
But it hardly seems worth it.
