OpenTelemetry, without the vendor lock-in: Introducing full observability for Open Source and Self-Hosted Flagsmith customers

Flagsmith has integrated OpenTelemetry (OTel) into its Open Source and Enterprise Editions, enhancing its self-hosted feature flag platform with distributed tracing and structured logs that complement existing Prometheus metrics. This integration allows users to enable OTel instrumentation with a single environment variable, providing a vendor-neutral, open-standards observability stack that includes metrics, traces, and logs without runtime overhead if the exporter endpoint is not configured. With Prometheus handling time-series metrics and Grafana providing visualization and alerting, this setup eliminates the need for separate tools and translation layers, thereby simplifying data correlation across systems. The OTel Collector facilitates data processing and forwarding to multiple destinations like Grafana Tempo, Loki, and other compatible backends, offering flexibility without vendor lock-in. This development underscores the growing adoption of OpenTelemetry as a standard for observability in self-hosted environments, providing insights into system performance and helping prevent minor issues from escalating.
