July 2025: Delivered the ElasticAPM Processor expansion and reintroduction in elastic/opentelemetry-collector-components, enabling cross-domain enrichment across traces, logs, and metrics with ECS compatibility and an improved metadata translation layer. Implemented a new config/factory to support consistent deployment and observability improvements, and established a deprecation-friendly path from the legacy ElasticTrace processor to ease migrations for users. This work strengthens observability coverage, reduces fragmentation, and accelerates onboarding for users adopting Elastic APM workflows. Two commits underpinning this effort: - c0ab45d18bb29aa5b6c8dc91bd5e73211dae08b7: Rename elastictrace processor to elasticapm and extend to logs and metrics (#634) - 20bd693fcdd52f7d36da5bd38255dc9cc3794196: Adding back elastictrace processor for smooth deprecation (#665)

June 2025 – Monthly summary for elastic/opentelemetry-collector-components. Key features delivered: - APM Metrics Support and Translation to OpenTelemetry: added mapping of Elastic APM breakdown metrics to OpenTelemetry metrics, refactored the receiver logic to translate Elastic APM metric data into OpenTelemetry metrics, including handling for span breakdown metrics and various metric types (counters, gauges). Updated tests and test data to cover the new translation paths. Major bugs fixed: - No major defects reported this month; focus remained on feature enablement and test coverage. Overall impact and accomplishments: - Enabled observability pipelines to ingest Elastic APM data directly as OpenTelemetry metrics, improving consistency across telemetry pipelines, accelerating migration paths, and enabling richer dashboards. The receiver refactor reduces maintenance burden and improves reliability of metric translation. Technologies/skills demonstrated: - OpenTelemetry concepts and data model, Elastic APM integration, Go-based receiver logic, metrics translation, and test-driven development with comprehensive test data updates.
