ASP.NET Core is an open source web development framework that enables you to develop .NET applications on macOS, Linux, and Windows machines. The introduction of .NET Core in 2016 dramatically increased the number of ways to build and deploy .NET applications. This means that you need the ability to easily monitor application performance across a wide variety of platforms, such as Docker containers.

Being able to track requests across all of an application’s service and process boundaries helps you identify issues with services and their dependencies, such as slow database calls or overloaded servers. In this post, we’ll walk through how to instrument a sample containerized ASP.NET Core application to send traces to Datadog for monitoring by:

• Deploying the Datadog Agent in a Docker container to collect application traces
• Instrumenting an application running on Linux or Windows containers with Datadog’s .NET tracer

Datadog’s .NET tracer uses the .NET profiling APIs to add out-of-the-box instrumentation for many common libraries and programming languages used for both .NET Core and .NET frameworks, including VB.NET, C#, and F#. Once instrumented, your application will automatically send traces to the Datadog Agent, which aggregates and enhances them with additional metadata from the host before forwarding them to Datadog. For full details on the .NET tracer, check out our documentation.
