OpenTelemetry Survey Reveals Maturing Interoperability with Prometheus, Easing Metrics Adoption

The OpenTelemetry project recently released the results of a 2026 survey focusing on the interoperability between OpenTelemetry and Prometheus for metrics. The survey, which gathered insights from users actively employing OpenTelemetry for metrics with Prometheus-adjacent backends, reveals a notable improvement in how these two critical observability components work together. Key findings indicate that the perceived ease-of-use has risen significantly since a similar survey in 2024, with a substantial decrease in respondents finding it difficult to use them in conjunction. This development is highly significant for practitioners in the cloud-native and DevOps spaces. It addresses a long-standing challenge of integrating diverse monitoring tools without sacrificing existing investments or introducing excessive complexity. For many organizations, Prometheus has been the de facto standard for infrastructure monitoring, while OpenTelemetry offers a unified approach to application instrumentation across various languages and frameworks. The improved interoperability means that teams can now more seamlessly combine the strengths of both, fostering a more comprehensive observability strategy. This reduces the pressure to choose one over the other and instead encourages a hybrid approach that leverages the best aspects of each system. This trend aligns with the broader movement towards standardized and vendor-neutral observability, a core tenet of OpenTelemetry itself. The project's graduation to the CNCF's highest maturity level in May 2026 underscored its readiness for widespread production use and its role in simplifying observability by providing a single standard for telemetry data collection. The continued focus on interoperability, as evidenced by this survey, demonstrates OpenTelemetry's commitment to integrating with the existing ecosystem rather than forcing a complete overhaul. This pragmatic approach is essential for driving adoption in enterprises with established monitoring practices. The OTel Collector, for instance, plays a crucial role in processing and exporting metrics to various backends, including Prometheus. In practice, this means that engineers can confidently explore OpenTelemetry SDKs for instrumenting their applications, knowing that the resulting metrics can be easily integrated into their existing Prometheus-based monitoring dashboards and alerts. The survey highlights that OpenTelemetry SDKs are now the most-used method for application instrumentation, while Prometheus exporters remain dominant for infrastructure. This suggests a natural division of labor where both tools coexist and complement each other. Practitioners should pay close attention to the continued development of OpenTelemetry's Prometheus receiver and exporter capabilities, as well as the OpenTelemetry Collector's role in facilitating this interoperability. The ability to use a "vanilla stack" of either Prometheus or the OTel Collector for processing further simplifies deployment, reducing the need for complex custom configurations. This evolution empowers teams to build more resilient and observable systems with less operational overhead.
