Includes a small Telemetry wrapper for the dotnet ActivitySource, to make it more compatible with other OpenTelemetry applications in other languages.
Saturn.OpenTelemetry is a library that extends the Saturn Web Application framework with functionality to integrate OpenTelemetry for distributed tracing and metrics. This means that you can easily add observability to your Saturn applications, allowing you to monitor and analyze the performance and behavior of your services.
Inspired by the OpenTelemetry .NET SDK, but adapted to work seamlessly with Saturn's functional programming model and F# syntax.
Add the Saturn.OpenTelemetry NuGet package to your project:
dotnet add package Saturn.OpenTelemetryBasic use case:
open Saturn
open Saturn.OpenTelemetry
// General OpenTelemetry Configuration
let otelConfig: OtelConfig = {
Endpoint = "http://localhost:4317"
AppId = "Example"
Namespace = "Saturn"
Version = "1.0.0"
}
// Add OpenTelemetry to the Saturn pipeline
let app = application {
use_router webAppRouter
url "http://0.0.0.0:8085/"
use_otel (
configure_otel {
// These are required
settings otelConfig
// These are optional and can be used to enable specific features
// use_efcore
// use_redis
// use_openfga
}
)

0You can deploy the LGTM (Loki, Grafana, Tempo and Mirmir) stack locally for development purposes.
docker run -p 3002:3000 -p 4317:4317 -p 4318:4318 --rm -ti grafana/otel-lgtmThis will spin up a container listening for OTEL traces on port 4317 and 4318 and can be accessed on port 3002.
A slightly pimped version of the classic otel-lgtm container preconfigured with DotNet and Dapr dashboards, is available here.
