OpenTelemetry-Go is the Go implementation of OpenTelemetry, providing APIs and SDKs for Go applications to measure performance and behavior by collecting distributed traces, metrics, and logs. The project delivers a unified set of APIs that enable developers to instrument their applications and export telemetry data to observability platforms without being locked into specific vendors or tools.
The project maintains stable status for both traces and metrics signals, while logs functionality is currently in beta. According to the README, the implementation supports Go versions 1.25 and 1.26 across multiple operating systems and architectures including Ubuntu, macOS, and Windows on amd64, 386, and arm64 platforms. The project follows Go's upstream compatibility policy, supporting each major Go release until two newer major releases exist, and removes compatibility testing for archived versions in a structured manner.
The repository provides four officially supported exporters for sending telemetry data: OTLP which supports logs, metrics, and traces; Prometheus for metrics only; stdout for logs, metrics, and traces; and Zipkin for traces. This modular exporter architecture allows users to choose the observability platform that best fits their needs. The instrumentation process involves two main steps: first instrumenting the application using either official instrumentation libraries from the opentelemetry-go-contrib repository or the core Go otel package, and second configuring an appropriate exporter to send collected data to observability platforms.
GitGenius activity data reveals significant ongoing development and maintenance.
