An OpenTelemetry backend in a Docker image: Introducing grafana/otel-lgtm

Grafana Labs introduces the grafana/otel-lgtm Docker image, a preconfigured OpenTelemetry backend aimed at facilitating open-source monitoring and integration testing. This image integrates with the OpenTelemetry Collector, Prometheus, Loki, Tempo, and Grafana, allowing users to collect, store, and visualize telemetry data such as metrics, logs, and traces. It supports both gRPC and HTTP protocols for receiving OpenTelemetry signals and provides example Grafana dashboards for quick setup. Although designed for development and testing environments, grafana/otel-lgtm simplifies the process of running integration tests by enabling users to verify telemetry signals through Grafana’s HTTP API. The image is open-source, available on Docker Hub, and supports community contributions, with plans for further enhancements and integration with projects like Quarkus.
