The New Relic One observability platform has adopted open instrumentation, allowing it to collect telemetry data from both open and proprietary sources. The company has built an adapter for Istio, a popular service mesh, to integrate with its telemetry engine, Mixer, and send curated telemetry data to the platform. This adapter uses the go-telemetry-sdk to gather metric and trace data, including Istio's metric and trace telemetry, and sends it to New Relic as open source dimensional metrics. The adapter can be used by any service running in the Istio service mesh without requiring reconfiguration or a New Relic agent. The adapter is now available on GitHub and has been open sourced as part of New Relic's initiative to promote open instrumentation.
