OpenTelemetry Collector

The OpenTelemetry Collector is a vendor-neutral server written in Go. It receives telemetry data, processes it and exports it to one or more backends. Applications instrumented with OpenTelemetry SDKs send it OTLP. The agent deployment page places the Collector beside the application, on the same host, as a sidecar or DaemonSet, and the gateway page describes Collector instances running as a standalone service. The install docs give a prebuilt binary, a Docker image, a Kubernetes install and a build from source. The core Docker image is otel/opentelemetry-collector. The project describes itself as a Cloud Native Computing Foundation project.

Worth knowing

The repository holds the core library and a build target for the core distribution. The release images on ghcr.io come from a separate releases repository.
