Siavash Safi	a89c665f47	feat(notifier): independent alertmanager sendloops (#16355) ... * notifier: unit test for dropping throughput on stuck AM Ref: https://github.com/prometheus/prometheus/issues/7676 Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> Signed-off-by: Siavash Safi <siavash@cloudflare.com> * chore(notifier): remove year from copyrights Signed-off-by: Siavash Safi <siavash@cloudflare.com> * feat(notifier): independent alertmanager sendloops Independent Alertmanager sendloops avoid issues with queue overflowing when one or more Alertmanager instances are unavailable which could result in lost alert notifications. The sendloops are managed per AlertmanagerSet which are dynamically added/removed with service discovery or configuration reload. The following metrics now include an extra dimention for alertmanager label: - prometheus_notifications_dropped_total - prometheus_notifications_queue_capacity - prometheus_notifications_queue_length This change also includes the test from #14099 Closes #7676 Signed-off-by: machine424 <ayoubmrini424@gmail.com> Signed-off-by: Siavash Safi <siavash@cloudflare.com> --------- Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> Signed-off-by: Siavash Safi <siavash@cloudflare.com> Signed-off-by: machine424 <ayoubmrini424@gmail.com> Co-authored-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com>	2026-01-20 10:33:07 +01:00

Julien Pivotto	01637b47b0	Fix multi-arch support for distroless Docker image ... The distroless Dockerfile was using a hardcoded SHA256 digest that referenced only the amd64 image, preventing builds for other architectures. This caused the main-distroless tag to only publish amd64 images while the regular main tag had all 5 architectures. Changes: - Use architecture-specific image tags (nonroot-${DISTROLESS_ARCH}) instead of SHA256 digest to enable multi-arch manifest resolution - Add DISTROLESS_ARCH build arg to handle architecture name mapping (armv7 -> arm) between Prometheus and distroless conventions - Move ARG declarations before FROM to support variable substitution Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com>	2026-01-19 15:58:37 +01:00

Arve Knudsen	572f247b4d	tsdb: add auto-cleanup to newTestHead and remove redundant cleanup calls (#17890) ... Add automatic cleanup to newTestHeadWithOptions so that heads created with newTestHead are automatically closed when the test ends. This simplifies test code by removing the need for manual cleanup in most cases. Changes: - Add t.Cleanup in newTestHeadWithOptions immediately after creating the head, using _ = h.Close() to handle double-close gracefully - Remove redundant t.Cleanup, defer, and explicit Close calls from tests that use newTestHead - Add cleanup for heads created with NewHead directly in restart patterns (e.g., restartHeadAndVerifySeriesCounts, startHead) Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com>	2026-01-19 12:57:05 +01:00

Julien Pivotto	66bb47ade6	fuzzing: fix artifact path and experimental parser flags ... Fix two issues in fuzzing infrastructure: - Correct artifact upload path from promql/testdata/fuzz to util/fuzzing/testdata/fuzz to match where Go stores crash artifacts - Fix GetCorpusForFuzzParseExpr to preserve original parser flag values instead of always resetting them to false, which was disabling experimental features before actual fuzzing ran Signed-off-by: Julien Pivotto <291750+roidelapluie@users.noreply.github.com>	2026-01-16 12:07:16 +01:00

Arve Knudsen	4afa76d083	OTLP: label caching for OTLP-to-Prometheus conversion to reduce allocations and improve latency (#17860) ... * otlptranslator: add label caching for OTLP-to-Prometheus conversion Add per-request caching to reduce redundant computation and allocations during OTLP metric conversion: 1. Per-request label sanitization cache: Cache sanitized label names within a request to avoid repeated string allocations for commonly repeated labels like __name__, job, instance. 2. Resource-level label caching: Precompute and cache job, instance, promoted resource attributes, and external labels once per ResourceMetrics boundary instead of for each datapoint. 3. Scope-level label caching: Precompute and cache scope metadata labels (otel_scope_name, otel_scope_version, etc.) once per ScopeMetrics boundary. 4. LabelNamer instance caching: Reuse the LabelNamer struct across datapoints within the same resource context. These optimizations significantly reduce allocations and improve latency for OTLP ingestion workloads with many datapoints per resource/scope. --------- Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	2026-01-16 10:30:05 +00:00
Julius Volz	ded3a8c309	UI: Fix broken Y axis after graph page reload (#17869) ... * UI: Fix broken Y axis after graph page reload The new `y_axis_min` setting was always encoded into the URL, even if its value was `null` (in which case it would be set to an empty string parameter). On the decoding side, this wasn't taken into account correctly, and we tried to parse the empty string as a float, causing completely broken graphs showing nothing after reloading the graph page with such URL parameters. I'm doing two things now: * For the future, only encode the Y axis min into the URL if it's set at all, similar as we do for the `end_input` and `moment_input` fields. * On the decoding side, accommodate people (at least for now) who already saved some links with the empty `y_axis_min` parameter by treating an empty string as `null` instead of a number.

Arve Knudsen	a85a8998c9	otlptranslator: fix BenchmarkPrometheusConverter_FromMetrics (#17866) ... The benchmark was passing appendMetadata=false to NewCombinedAppender, which caused UpdateMetadata to never be called on the underlying noOpAppender. This resulted in app.metadata always being 0, failing the assertion that metadata count should be positive. Fix by enabling metadata appending in the benchmark.
