It provides a vendor-agnostic standard for collecting telemetry data—metrics, logs, and traces—so you can understand exactly what your code is doing in production. In this article, I'll show you how to quickly integrate OpenTelemetry into an existing .NET Core project, define the data you want to collect, and use the Aspire Dashboard to visualize all your traces.
