Prometheus and OpenTelemetry interoperability in 2026 - Survey results

We ran a survey asking users of OpenTelemetry and Prometheus how they collect, process, and store metrics. The goal was to understand, with real usage data rather than assumptions, how far the ecosystem has moved and whether the interoperability still causes friction. Key takeaways Interoperability has measurably improved since our 2024 survey : the average ease-of-use rating rose from 3.1 to 3.6, the equivalent of one in two respondents rating a whole category higher, and the share of respondents finding the two hard to use together fell from 29% to 10%.
