some metrics broken when sampling frequency >= 1min

[nfi-opsguru]

Certain metrics don't appear when the prometheus instance in question has a sampling interval >= 1min.

Had a look into and it's probably because rate queries are hard-coded to 1m:

lens/src/main/prometheus/lens.ts

Line 14 in bff5282

readonly rateAccuracy: string = "1m";

Indeed if I query this by hand, it is empty. rate needs a window >= 2 * sampling interval.

Pretty sure #5052 is the same sort of issue.

You'd probably have to make that configurable or derive it somehow, like Grafana does.
