Installation

Kindly run the command below to install the package:

dotnet add package ApiToolkit.Net

Setup OpenTelemetry

Run the following command to install the OpenTelemetry auto instrumentation for .NET:

# Download the bash script
curl -sSfL https://github.com/open-telemetry/opentelemetry-dotnet-instrumentation/releases/latest/download/otel-dotnet-auto-install.sh -O

# Install core files
sh ./otel-dotnet-auto-install.sh

# Enable execution for the instrumentation script
chmod +x $HOME/.otel-dotnet-auto/instrument.sh

# Setup the instrumentation for the current shell session
. $HOME/.otel-dotnet-auto/instrument.sh

OpenTelemetry Configuration

After installating .NET autoinstrumentation packages, you can configure the OpenTelemetry instrumentation by setting the following environment variables:

export OTEL_EXPORTER_OTLP_ENDPOINT="http://otelcol.apitoolkit.io:4317" # Specifies the endpoint to send the traces to.
export OTEL_DOTNET_AUTO_TRACES_ADDITIONAL_SOURCES="APItoolkit.HTTPInstrumentation" # The apitoolkit instrumentation  activity resource.
export OTEL_SERVICE_NAME="my-service" # Specifies the name of the service.
export OTEL_RESOURCE_ATTRIBUTES="at-project-key={ENTER_YOUR_API_KEY_HERE}" # Adds your API KEY to the resource.
export OTEL_EXPORTER_OTLP_PROTOCOL="grpc" # Specifies the protocol to use for the OpenTelemetry exporter.

After setting the environment variables, build and run your application and you should see the logs, traces and metrics in the APIToolkit dashboard.

SDK Configuration

The SDK allows you to capture the request and response bodies, errors, outgoing requests and more.

eg:

using ApiToolkit.Net;

// Initialize the APItoolkit client
var config = new Config
{
    Debug = false,
    Tags = new List<string> { "environment: production", "region: us-east-1" },
    ServiceVersion: "v2.0",
};
var client = await APIToolkit.NewClient(config);
// END Initialize the APItoolkit client
// Register the middleware to use the initialized client
app.Use(async (context, next) =>
{
    var apiToolkit = new APIToolkit(next, client);
    await apiToolkit.InvokeAsync(context);
});

# app.UseEndpoint(..)
# other middleware and logic
# ...
