Modifying metric values based on a static mapping

[jp-moller]

I have some OIDS that for some reason instead of just returning the value, returns a mapping to a value. Below is an example:

Connected RF Bandwidth:
1 for 20 MHz,
2 for 40 MHz,
3 for 10 MHz,
4 for 5 MHz,
5 for 80 MHz

Why they didn't just return 20, 40, 10, 5 or 80 is beyond me.

Is there a way that I can convert these values to their actual values via the exporter? Can I fake a lookup table or do an override that can do this? I'd prefer to not have to do it in recording rules if I can avoid it.

So I have found if you just throw a hack and slash approach to regex, it will work

regex_extracts:
"":
- value: 80
regex: ^(?:(5))$
- value: 5
regex: ^(?:(4))$
- value: 10
regex: ^(?:(3))$
- value: 40
regex: ^(?:(2))$
- value: 20
regex: ^(?:(1))$
- value: 0
regex: ^(?:(.*))$
