beorn7	ad7d1aed99	Phase out native histogram feature flag ... The detailed plan for this is laid out in https://github.com/prometheus/prometheus/issues/16572 . This commit adds a global and local scrape config option `scrape_native_histograms`, which has to be set to true to ingest native histograms. To ease the transition, the feature flag is changed to simply set the default of `scrape_native_histograms` to true. Further implications: - The default scrape protocols now depend on the `scrape_native_histograms` setting. - Everywhere else, histograms are now "on by default". Documentation beyond the one for the feature flag and the scrape config are deliberately left out. See https://github.com/prometheus/prometheus/pull/17232 for that.

Julien	4199c2f45a	Add anchored and smoothed to vector selectors. (#16457) ... * Add anchored and smoothed to vector selectors. This adds "anchored" and "smoothed" keywords that can be used following a matrix selector. "Anchored" selects the last point before the range (or the first one after the range) and adds it at the boundary of the matrix selector. "Smoothed" applies linear interpolation at the edges using the points around the edges. In the absence of a point before or after the edge, the first or the last point is added to the edge, without interpolation. *Exemple usage* * `increase(caddy_http_requests_total[5m] anchored)` (equivalent of *caddy_http_requests_total - caddy_http_requests_total offset 5m* but takes counter reset into consideration) * `rate(caddy_http_requests_total[step()] smoothed)` Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com> * Update docs/feature_flags.md Co-authored-by: Charles Korn <charleskorn@users.noreply.github.com> Signed-off-by: Julien <291750+roidelapluie@users.noreply.github.com> * Smoothed/Anchored rate: Add more tests Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com> * Anchored/Smoothed modifier: error out with histograms Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com> --------- Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com> Signed-off-by: Julien <291750+roidelapluie@users.noreply.github.com> Co-authored-by: Charles Korn <charleskorn@users.noreply.github.com>	2025-09-25 11:34:59 +02:00

machine424	184c7eb918	storage/remote: compute highestTimestamp and dataIn at QueueManager level ... Because of relabelling, an endpoint can only select a subset of series that go through WriteStorage Having a highestTimestamp at WriteStorage level yields wrong values if the corresponding sample won't even make it to a remote queue. Currently PrometheusRemoteWriteBehind is based on that, and would fire if an endpoint is only interested in a subset of series that take time to appear. A "prometheus_remote_storage_queue_highest_timestamp_seconds" that only takes into account samples in the queue is introduced, and used in PrometheusRemoteWriteBehind and dashboards in documentation/prometheus-mixin Same applies to samplesIn/dataIn, QueueManager should know more about when to update those; when data is enqueued. That makes dataDropped unnecessary, thus help simplify the logic in QueueManager.calculateDesiredShards() Signed-off-by: machine424 <ayoubmrini424@gmail.com>	2025-09-01 13:19:24 +02:00

beorn7	747c5ee2b1	Apply analyzer "modernize" to the whole codebase ... See https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize for details. This ran into a few issues (arguably bugs in the modernize tool), which I will fix in the next commit, so that we have transparency what was done automatically. Beyond those hiccups, I believe all the changes applied are legitimate. Even where there might be no tangible direct gain, I would argue it's still better to use the "modern" way to avoid micro discussions in tiny style PRs later.

Nicolas Peugnet	4eca0942f2	Clarify the docs of promtool --{min,max}-time options ... State explicitely what kind of timestamps are expected for the --min-time and --max-time options of promtool tsdb commands. This is especially important for the dump-openmetrics command as users could otherwise mistakenly think it would be in seconds, like the OpenMetrics timestamps themselves.

Julien Pivotto	7370d62acf	PromQL: allow arithmetic in durations in PromQL parser ... Updated the parser to allow calculations in PromQL durations. This enables durations in the form of: rate(http_requests_total[10m+2s]) The computation of the calculations is done directly at the parse level and does not hit the PromQL Engine. The lexer has also been updated and improved, in particular for subqueries. Buxfix: rate(http_requests_total[0]) is no longer allowed.
