Julien	7ebda924b8	fix(web): properly format sub-millisecond durations in target status page ... Previously, scrapes durations that are very short (e.g., connection refused) could show as empty (durations under 1 millisecond). This commit ensures that sub-millisecond durations are correctly displayed as "0ms" or "1ms" when necessary. - Adjusted `humanizeDuration` to round sub-millisecond durations to the nearest millisecond. - Updated unit tests to verify the correct handling of sub-millisecond values.

beorn7	6fcd225aee	promql(native histograms): Introduce exponential interpolation ... The linear interpolation (assuming that observations are uniformly distributed within a bucket) is a solid and simple assumption in lack of any other information. However, the exponential bucketing used by standard schemas of native histograms has been chosen to cover the whole range of observations in a way that bucket populations are spread out over buckets in a reasonably way for typical distributions encountered in real-world scenarios. This is the origin of the idea implemented here: If we divide a given bucket into two (or more) smaller exponential buckets, we "most naturally" expect that the samples in the original buckets will split among those smaller buckets in a more or less uniform fashion. With this assumption, we end up with an "exponential interpolation", which therefore appears to be a better match for histograms with exponential bucketing. This commit leaves the linear interpolation in place for NHCB, but changes the interpolation for exponential native histograms to exponential. This affects `histogram_quantile` and `histogram_fraction` (because the latter is more or less the inverse of the former). The zero bucket has to be treated specially because the assumption above would lead to an "interpolation to zero" (the bucket density approaches infinity around zero, and with the postulated uniform usage of buckets, we would end up with an estimate of zero for all quantiles ending up in the zero bucket). We simply fall back to linear interpolation within the zero bucket. At the same time, this commit makes the call to stick with the assumption that the zero bucket only contains positive observations for native histograms without negative buckets (and vice versa). (This is an assumption relevant for interpolation. It is a mostly academic point, as the zero bucket is supposed to be very small anyway. However, in cases where it _is_ relevantly broad, the assumption helps a lot in practice.) This commit also updates and completes the documentation to match both details about interpolation. As a more high level note: The approach here attempts to strike a balance between a more simplistic approach without any assumption, and a more involved approach with more sophisticated assumptions. I will shortly describe both for reference: The "zero assumption" approach would be to not interpolate at all, but _always_ return the harmonic mean of the bucket boundaries of the bucket the quantile ends up in. This has the advantage of minimizing the maximum possible relative error of the quantile estimation. (Depending on the exact definition of the relative error of an estimation, there is also an argument to return the arithmetic mean of the bucket boundaries.) While limiting the maximum possible relative error is a good property, this approach would throw away the information if a quantile is closer to the upper or lower end of the population within a bucket. This can be valuable trending information in a dashboard. With any kind of interpolation, the maximum possible error of a quantile estimation increases to the full width of a bucket (i.e. it more than doubles for the harmonic mean approach, and precisely doubles for the arithmetic mean approach). However, in return the _expectation value_ of the error decreases. The increase of the theoretical maximum only has practical relevance for pathologic distributions. For example, if there are thousand observations within a bucket, they could _all_ be at the upper bound of the bucket. If the quantile calculation picks the 1st observation in the bucket as the relevant one, an interpolation will yield a value close to the lower bucket boundary, while the true quantile value is close to the upper boundary. The "fancy interpolation" approach would be one that analyses the _actual_ distribution of samples in the histogram. A lot of statistics could be applied based on the information we have available in the histogram. This would include the population of neighboring (or even all) buckets in the histogram. In general, the resolution of a native histogram should be quite high, and therefore, those "fancy" approaches would increase the computational cost quite a bit with very little practical benefits (i.e. just tiny corrections of the estimated quantile value). The results are also much harder to reason with. Signed-off-by: beorn7 <beorn@grafana.com>	2024-09-19 14:19:10 +02:00

Joshua Hesketh	b6107cc888	Make rate possible non-counter annotation consistent (#14910) ... * Make rate possible non-counter annotation consistent Previously a PossibleNonCounterInfo annotation would be left in cases where a range-vector selects 1 float data point, even if no more points are selected in order to calculate a rate. This change ensures an output float exists before emitting such an annotation. This fixes an inconsistency where a series with mixed data (ie, a float and a native histogram) would emit an annotation without any points. For example, ``` load 1m series{label="a"} 1 {{schema:1 sum:10 count:5 buckets:[1 2 3]}} eval instant at 1m rate(series[1m1s]) ``` Would have a PossibleNonCounterInfo annotation. Wheras ``` load 1m series{label="a"} {{schema:1 sum:10 count:5 buckets:[1 2 3]}} {{schema:1 sum:15 count:10 buckets:[1 2 3]}} eval instant at 1m rate(series[1m1s]) ``` Would not. --------- Signed-off-by: Joshua Hesketh <josh@nitrotech.org>	2024-09-18 10:21:25 +00:00
