OpenTelemetry together with the Grafana stack

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

Note

Instead of using docker compose to start up the environment, you can also take a look at the repository using .NET Aspire as orchestrator
It is available on the aspire branch: aspire orchestrated version

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

Components used:

  • ASP.NET Web API for demo services
  • RabbitMq as message queue
  • 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

Remarks:

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.

Usage:

docker compose -f docker-compose-mac.yml --profile all up -d
docker compose -f docker-compose-mac.yml --profile all down
