July 2025: Focused on documentation quality for grafana/tempo, delivering a precise, low-risk fix that improves configuration note accuracy and user understanding. The change reduces potential support queries and aids onboarding by removing a confusing typo.

Monthly summary for 2025-06 focusing on grafana/mimir. Key feature delivered: introduced a native histogram metric cortex_distributor_sample_delay_seconds to measure the delay between ingested samples and wall clock, enabling per-user visibility into sample ingestion latency for better troubleshooting and performance monitoring in the distributor component. Major bugs fixed: none reported for this scope in 2025-06. Overall impact: improved observability and troubleshooting capabilities for ingestion latency in the distributor path, supporting more reliable latency monitoring and SLA adherence. Technologies/skills demonstrated: instrumentation of metrics with native histograms, Go-based code changes in the distributor component, commit-based development and traceability (commit d1438d1c5b49b4a04ffa54fa5b64c370f565b77f; PR #11573).
