This repository is a work in progress, about having an observability stack for your microservices environment with .NET Aspire.

If you want to know/learn more, also check out my Pluralsight course on the subject here https://www.pluralsight.com/library/courses/opentelemetry-grafana-observability

• ASP.NET Web API for demo services
• RabbitMq as message queue ( still todo in the Aspire variant )
• OpenTelemetry Collector as middle man for tracing and logs
• BlackBox and Prometheus for service metrics and health checks
• Loki for log aggregation
• Tempo for tracing aggregation
• Grafana for overall dashboarding

To be able to get the environment functioning correctly be sure to have following setting active in Docker Desktop: Add the *.docker.internal names to the host's etc/hosts file

For alert provisioning we can extract the JSON through use of the Grafana API: https://grafana.com/docs/grafana/latest/developers/http_api/alerting_provisioning/

This sample is sending logs from SeriLog to OpenTelemetry in OTLP format and OpenTelemetry will pass it along to Loki.

The project will start through dotnet Aspire with following command

dotnet run --project otel.AppHost
