April 2026 monthly summary for grafana/alloy focusing on Pyroscope EBPF metric registration lifecycle and reliability improvements. Delivered a bug fix that defers Prometheus metrics registration until after successful construction of the pyroscope.ebpf component, preventing registration of unused metrics when construction fails. This change improves observability accuracy, reduces startup-time noise, and eliminates misleading metrics exposure during initialization errors. Tests were updated to cover the new behavior, and the PR (#5540) references issue #5156 to prevent regressions. Result: more stable initialization, clearer error signals, and better business value from reliable metrics exposure.

September 2025 summary for jenkinsci/opentelemetry-plugin: Delivered Grafana Example Enhancements and Loki/Jaeger UIDs with Trace-to-Log (Loki V3), updated log format, and fixed integration links to enable trace-to-logs. These changes simplify configuration, improve end-to-end observability, and enhance compatibility between Loki, Jaeger, and Grafana, delivering measurable business value for monitoring and troubleshooting.
