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.

Arve Knudsen	16703766f4	promql: fix info() returning empty when filtering by overlapping labels (#17817) ... When filtering by a label that exists on both the input metric and target_info (e.g., info(metric, {host_name="orbstack"}) where host_name exists on both), the function incorrectly returned empty results. The bug was in combineWithInfoVector: when no new labels were added (because they all overlapped with base metric labels), the code entered the "no match" filtering block even though an info series WAS matched. The fix checks len(seenInfoMetrics) == 0 to correctly identify when no info series matched. If an info series matched (seenInfoMetrics is non-empty), the series is kept even if no new labels were added.
