Azure's integration with OpenTelemetry provides a suite of products for:
This article guides you through our OpenTelemetry offerings to help you understand Microsoft’s strategic investments.
For more information about OpenTelemetry on Azure, see our OpenTelemetry Roadmap.
The Azure Monitor OpenTelemetry Distro is Microsoft’s customized, supported, and open-sourced version of the OpenTelemetry software development kits (SDKs). It supports .NET, Java, JavaScript (Node.js), and Python. We recommend the Azure Monitor OpenTelemetry Distro for most customers, and we continue to invest in adding new capabilities to it.
It focuses on ease-of-enablement by bundling together:
In addition, Azure Monitor OpenTelemetry Distro-based automatic instrumentation solutions are integrated into App Service for Java and Python apps and into Java Functions.
Azure SDKs are instrumented with OpenTelemetry APIs to power end-to-end observability. All supported languages are instrumented to emit OpenTelemetry HTTP and/or Messaging Tracing Semantics; .NET and Java are being instrumented to emit OpenTelemetry HTTP Metrics Semantics.
The .NET OpenTelemetry implementation uses logging, metrics, and activity APIs in the framework for instrumentation. The OpenTelemetry SDK collects telemetry from those APIs and other sources (via instrumentation libraries) and then exports the data to an application performance monitoring (APM) system for storage and analysis.
Azure Monitor pipeline at edge is a powerful solution designed to facilitate high-scale data ingestion and routing from edge environments to seamlessly enable observability across cloud, edge, and multicloud. It uses the OpenTelemetry Collector. Currently, in public preview, it can be deployed on a single Arc-enabled Kubernetes cluster, and it can collect OpenTelemetry Protocol (OTLP) logs.
OpenTelemetry Collector Azure Data Explorer Exporter is a data exporter component that can be plugged into the OpenTelemetry Collector. It supports ingestion of data from many receivers into to Azure Data Explorer, Azure Synapse Data Explorer, and Real-Time Analytics in Fabric.
Azure Functions allows exporting log and trace data in OTLP format. It supports telemetry from both the host process and the worker process. When enabled, the data can be sent to any OpenTelemetry-compliant endpoints.
.NET Aspire is an opinionated cloud-native stack that includes observability by default with OpenTelemetry. Part of it's a "Developer Dashboard" to observe OpenTelemetry signals in real-time during debugging. It collects logs, metrics, and traces using OTLP from applications of any OpenTelemetry-supported languages besides .NET.
Azure Monitor Application Insights is Azure’s APM that supports cloud-scale application monitoring and excels at observability for both cloud-native applications and VM-based applications. Application Insights provides experiences powered by OpenTelemetry to enhance the performance, reliability, and quality of your applications. For example, Application map is a visual overview of application architecture and components' interactions; Transaction search helps identify issues and optimize performance.
