- Traces: ASP.NET Core | Console
This repository includes multiple installable components, available on
NuGet. Each component has its
individual README.md file, which covers the instruction on how to install and
how to get started. To find all the available components, please take a look at
the src folder.
Here are the most commonly used components:
Here are the instrumentation libraries:
- ASP.NET Core
- gRPC client: Grpc.Net.Client
- HTTP clients: System.Net.Http.HttpClient and System.Net.HttpWebRequest
- SQL clients: Microsoft.Data.SqlClient and System.Data.SqlClient
Here are the exporter libraries:
- Console

See the OpenTelemetry registry and OpenTelemetry .NET Contrib repo for more components.
See Troubleshooting. Additionally check readme file for the individual components for any additional troubleshooting information.
OpenTelemetry .NET is designed to be extensible. Here are the most common extension scenarios:
- Building a custom instrumentation library.
- Building a custom exporter for logs, metrics and traces.
- Building a custom processor for logs and traces.
- Building a custom sampler for traces.
See CONTRIBUTING.md
