Dear Prometheans, So far, we have recommended Celsius as the base unit for temperatures, despite Kelvin being the SI unit. That was well justified by the overwhelming majority of use cases, where Kelvin would be just weird. I'd really like to see more scientific usage of Prometheus, so I was never super happy with that recommendation, but since it was just a recommendation, I could live with it.
Now Matt Layher came up with another, more technical use case: color temperature. Here, using Celsius would be even weirder. So there is a case where you clearly do not want to follow the suggestion of the linter, which is more in line with typical Prometheus use cases than my arguably somewhat far fetched time series for low-temperature experiments. Therefore, Matt suggested to make the metrics linter not complain about kelvin. I think this is a clearly defined problem with clear arguments and a clear disagreement between Brian Brazil on the one side and Matt and myself on the other side. The appropriate amount of effort has been spent to find a consensus. All arguments can be found in https://github.com/prometheus/client_golang/pull/761 and https://github.com/prometheus/docs/pull/1648 . I hereby call a vote for the following proposal: Allow Kelvin as a base unit in certain cases and update our documented recommendation and the linter code accordingly. (The changes may take the form of the two PRs out there, but the vote in about the general idea above, not the implementation detail.) The vote closes on 2020-06-04 20:00 UTC. -- Björn Rabenstein [PGP-ID] 0x851C3DA17D748D03 [email] [email protected] -- You received this message because you are subscribed to the Google Groups "Prometheus Developers" group.
