OpenTelemetry Announces First Wave of Beta Releases for Java, Go, JavaScript, Python, and .Net Components

The observability framework offers general-purpose APIs and SDKs to help developers generate, collect, and describe telemetry about distributed systems

SAN FRANCISCO--()--OpenTelemetry, an open source project created to provide a complete toolkit for cloud-native software observability, today announced the beta release of the first wave of supported languages, – including Java, JavaScript, Python, Go, and .Net – as well as the OpenTelemetry Collector.

By integrating tracing and metrics into a single system, OpenTelemetry provides a framework for building next generation observability platforms. OpenTelemetry simplifies the instrumentation of cloud-native software. Rich correlations between tracing and metrics help developers effectively conduct root cause analysis in distributed systems.

By qualifying for the beta launch, each component meets the following requirements:

  • The implementation of all features contained in the OpenTelemetry Specification, v0.3 or higher. This includes implementation of all API features, including traces, metrics, context propagation, and semantic conventions.
  • Support for exporting to OTLP, Jaeger, and Prometheus.
  • Instrumentation for at least one HTTP, gRPC, SQL, and web framework per language.
  • API, SDK, and getting started documentation.
  • Implementation of OTLP (an OpenTelemetry-native data format) in the OpenTelemetry Collector.

“At LightStep, we conducted research that found that 91 percent of developers are using or plan to use microservices, and almost all developers reported challenges in using microservices,” said Ben Sigelman, a member of the governance committee of OpenTelemetry and CEO of LightStep. “To address the challenges around performance and root cause analysis introduced by emerging technologies like microservices, we teamed up with experts in telemetry to standardize observability - making it much more accessible for development teams working in complex environments.”

“We’ve made significant progress on OpenTelemetry in the last few weeks as we’ve successfully added more languages for inclusion in the beta launch. We’ll continue to add more language-specific components to the project as we move forward, bringing us closer to our mission of instrumenting the world,” said Morgan McLean, co-founder of OpenCensus and OpenTelemetry and product manager at Google.
