Review comment:
> I think it'd be better to do opposite, disable everything and let end
users enable it, as in many cases default metrics would be sufficient to get
the picture of current status. Custom metrics are more likely auxiliary.
It makes sense, switching.
> So the ideal approach would be providing metric name with aggregation
method (sum, avg, min, max), but if it sounds to be complicated just for this
functionality, we could simply restrict to sum and explain it to config doc.
I think it's a good idea to have such functions but the question is what
exactly.
Sum and max makes sense but the other 2 I can't really imagine a use-case.
Maybe we can wait for real use-cases and add aggregation methods when it's
clear.
