Julius Volz	b57deb6eb0	Add /api/v1/format_query API endpoint for formatting queries (#11036 ) * Add /api/v1/format_query API endpoint for formatting queries This uses the formatting functionality introduced in https://github.com/prometheus/prometheus/pull/10544. I've chosen "query" instead of "expr" in both the endpoint and parameter names to stay consistent with the existing API endpoints. Otherwise, I would have preferred to use the term "expr".

beorn7	9eafed0f79	promql: Add `histogram_count` and `histogram_sum` This follow a simple function-based approach to access the count and sum fields of a native Histogram. It might be more elegant to implement “accessors” via the dot operator, as considered in the brainstorming doc [1]. However, that would require the introduction of a whole new concept in PromQL. For the PoC, we should be fine with the function-based approch. Even the obvious inefficiencies (rate'ing a whole histogram twice when we only want to rate each the count and the sum once) could be optimized behind the scenes. Note that the function-based approach elegantly solves the problem of detecting counter resets in the sum of observations in the case of negative observations. (Since the whole native Histogram is rate'd, the counter reset is detected for the Histogram as a whole.) We will decide later if an “accessor” approach is really needed. It would change the example expression for average duration in functions.md from histogram_sum(rate(http_request_duration_seconds[10m])) / histogram_count(rate(http_request_duration_seconds[10m])) to rate(http_request_duration_seconds.sum[10m]) / rate(http_request_duration_seconds.count[10m]) [1]: https://docs.google.com/document/d/1ch6ru8GKg03N02jRjYriurt-CZqUVY09evPg6yKTA1s/edit Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

beorn7	b39f2739e5	PromQL: Always enable negative offset and @ modifier This follows the line of argument that the invariant of not looking ahead of the query time was merely emerging behavior and not a documented stable feature.

beorn7	8fdfa52976	API: Promote remote-write-receiver to stable Since `/api/v1/write` is a mutating endpoint, we should still activate the remote-write-receiver explicitly. But we should do it in the same way as the other mutating endpoints, i.e. via a flag `--web.enable-remote-write-receiver`. This commit marks the feature flag as deprecated, i.e. it still works but logs a warning on startup. This enables users to seamlessly migrate. With the next minor release, we can start ignoring the feature flag (but still warn a user that is trying to use it). Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Julien Pivotto	e17d18a043	docs: Fix type of the histogram_quantile function (#7666 ) Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>	4 years ago
beorn7	cf698f71e5	Add an explanation for the quantile aggregation operator Sadly, just linking to the Histogram best practice document, as done for `histogram_quantile`, would be confusing here because the best practice document only deals with quantiles in the context of Histograms and Summaries, which is very different from the context of the `quantile` aggregator and `quantile_over_time` function, which is already a source of a lot of confusion. Thus, I think the least bad solution is to add a short explanation in this section directly. There isn't even a good resource on the internet we can link to. A lot of statisticians use φ-quantiles, but they don't have a generally accepted name for it. I have added the explanation after the other detailed explanations of `count_values`, `topk` and `bottomk`. I think that fits quite nicely into the flow.
