From bb741b58d3ef451ede8b2e04bf2dc16a35f80427 Mon Sep 17 00:00:00 2001 From: Paul Buetow Date: Wed, 31 Dec 2025 11:56:04 +0200 Subject: Increase Prometheus out-of-order window to 31 days MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Changes: - outOfOrderTimeWindow: 720h → 744h (30 days → 31 days) Rationale: Provides 1-day buffer for 30-day backfill operations to avoid edge case rejections where the oldest samples exceed the limit due to timing variations between data generation and ingestion. With this configuration: - 30-day benchmarks achieve 99.85% success rate (vs 50% with 720h) - Only 4/2592 batches rejected (first few batches slightly over 30d) - Allows safe backfilling of up to 30 days of historic data 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- f3s/prometheus/persistence-values.yaml | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'f3s') diff --git a/f3s/prometheus/persistence-values.yaml b/f3s/prometheus/persistence-values.yaml index 588e28a..966d963 100644 --- a/f3s/prometheus/persistence-values.yaml +++ b/f3s/prometheus/persistence-values.yaml @@ -36,10 +36,10 @@ prometheus: enableFeatures: - exemplar-storage - otlp-write-receiver - # Set out-of-order time window to 30 days + # Set out-of-order time window to 31 days (provides 1-day buffer for 30-day backfills) additionalScrapeConfigs: [] tsdb: - outOfOrderTimeWindow: 720h # 30 days + outOfOrderTimeWindow: 744h # 31 days additionalScrapeConfigsSecret: enabled: true name: additional-scrape-configs -- cgit v1.2.3
