Counters

76 observations, 1 of them a change, fewer than the 3 a trace needs

How big is this endpoint among the ones like it?

Calls counted in the trailing thirty days across the 2,245 endpoints in Identity that carry counters, binned on a logarithmic scale because the range runs over five orders of magnitude. The marked bin is this endpoint, at 1: 1,357 in the category are counted higher and 887 lower.

No trace is drawn of this endpoint’s own volume. Its counters have changed 1 time across 76 observations, and 3 changes are the fewest this site will draw a trace through, because two points and a guess are not a series. Every observation is in the JSON.
