Arve Knudsen	ef42c088ba	OTLP: Add configuration parameters to control label name translation (#17345) ... As a follow-up to #17344, add two configuration parameters for controlling label name translation, both defaulting to on for backwards compatibility (currently these behaviours are hardcoded as enabled): * otlp.label_name_underscore_sanitization => Prefix label names starting with a single underscore with key_ when translating OTel attribute names * otlp.label_name_preserve_multiple_underscores => Keep multiple consecutive underscores in label names when translating OTel attribute names Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com>	2025-10-22 08:27:35 +02:00

Linas Medžiūnas	44df626620	promql (histograms): reconcile mismatched NHCB bounds (#17278) ... Fixes #17255. The implementation happens mostly in the Add and Sub method, but the reconciliation works for all relevant operations. For example, you can now `rate` over a range wherein the custom bucket boundaries are changing. Any custom bucket reconciliation is flagged with an info-level annotation. --------- Signed-off-by: Linas Medziunas <linas.medziunas@gmail.com> Signed-off-by: Linas Medžiūnas <linasm@users.noreply.github.com>	2025-10-18 01:03:52 +02:00
Julius Volz	09e7111aa7	UI: Fix double-loading of API data on pages with slow rendering (#17357) ... Without `staleTime: Infinity`, the query data would be immediately marked stale, and in combination with the `gcTime: 0` setting and a brief unmount during data loading (via Suspense), the data would have to be reloaded a second time during/after the first real render. `gcTime: 0` + `staleTime: Infinity` should give us the desired behavior where data loaded for a page should be valid forever as long as that page is being displayed, but always thrown away (and later reloaded) whenever we navigate away and again to that page.

Julien Pivotto	c40a574197	discovery/ec2: Fix AWS SDK v2 credentials handling for EC2 and Lightsail discovery ... After the upgrade to AWS SDK v2, the EC2 and Lightsail service discovery stopped working when using the default AWS credential chain (environment variables, IAM roles, EC2 instance metadata, etc.). The issue was that the code unconditionally created a StaticCredentialsProvider with empty credentials when access_key and secret_key were not configured. In AWS SDK v2, this causes a "static credentials are empty" error and prevents the SDK from falling back to its default credential chain.

Julius Volz	b7c3a2194f	Fix formatting of range vector selectors with smoothed/anchored modifier ... The modifiers were already printed as part of the VectorSelector, so for: `foo[5m] anchored` ...the output was: `foo anchored[5m] anchored` Similar to how it was already done for `@` and `offset`, I now removed these modifiers in the copy of the vector selector that is used to print the matrix selector. I also removed some unused code that restored the copy of the vector selector after overwriting its fields. AFAICS there was no use in doing that, since it was a copy already that would just be thrown away after printing, and the original selector wasn't affected. I also removed an erroneous comment in `atOffset()` where no actual copying took place and no fields were overwritten. Signed-off-by: Julius Volz <julius.volz@gmail.com>	2025-10-17 12:23:53 +02:00
Julien Pivotto	99c926b810	promql: allow 'anchored' and 'smoothed' as metric and label names ... Add ANCHORED and SMOOTHED keywords to the maybe_label and metric_identifier rules in the parser grammar, allowing them to be used as metric names and label names, similar to other keywords like 'offset', 'step', and 'bool'. This fixes an issue where expressions like `anchored{job="test"}` and `sum by (smoothed) (some_metric)` would fail to parse.

Julius Volz	8b1bd7d6c3	ui: Allow viewing detailed relabeling steps for each discovered target ... This adds: * A `ScrapePoolConfig()` method to the scrape manager that allows getting the scrape config for a given pool. * An API endpoint at `/api/v1/targets/relabel_steps` that takes a pool name and a label set of a target and returns a detailed list of applied relabeling rules and their output for each step. * A "show relabeling" link/button for each target on the discovery page that shows the detailed flow of all relabeling rules (based on the API response) for that target. Note that this changes the JSON encoding of the relabeling rule config struct to output the original snake_case (instead of camelCase) field names, and before merging, we need to be sure that's ok :) See my comment about that at https://github.com/prometheus/prometheus/pull/15383#issuecomment-3405591487 Fixes https://github.com/prometheus/prometheus/issues/17283 Signed-off-by: Julius Volz <julius.volz@gmail.com>	2025-10-15 15:33:27 +02:00

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.
