100–109

We will need these to be configured with specific buckets as well (same as D7727)

124–145

f-strings can't be used as docstrings.

293

As you may have guessed from my comment on D7726, I think this should be set as a tag on a common metric, rather than generate a set of distinct metrics.

And this should be pushed as a "constant" tag to used on further calls to statsd in this loader, without having to bother with passing the list of tags around on all calls, e.g. the ones for the refs ratios.

I also wonder if this should be a couple of tags rather than a single one:

  • incremental_enabled = "True"/"False"
  • (when incremental_enabled == "True") incremental_snapshot_origin="self"/"parent"/"none"

Is it worth distinguishing "has parent, no snapshot found" no_previous_snapshot from "doesn't have parent, no snapshot found" no_parent_origin? If so, maybe we can add a has_parent tag?)

actually not relevant anymore, as I'll use the core's self.statsd

100–109

already fixed, and renamed to _percent as recommended in prometheus' documentation

124–145

aw, sad. anyway, I don't need them anymore now that I'm removing the STATSD_PREFIX.

293

already fixed too, but in a different way. I can do it your way too, if you prefer.

Is it worth distinguishing "has parent, no snapshot found" no_previous_snapshot from "doesn't have parent, no snapshot found" no_parent_origin?

I don't know, but there is no harm in storing it, is there?
