Observability Workŝhop

This is a sample project used to demonstrate how Observability can be implemented by using OpenTelemetry. A C2 diagram is available that describes the different components used and their interactions.

Components :

• OpenTelemetry Collector : to collect metrics from all components
• Prometheus / Grafana : to visualize metrics
• Jaeger : to visualize distributed traces
• Elasticsearch / Elastic APM / Kibana : to visualize logs and distributed traces
• Sentry : to monitor unexpected errors
• Redis
• MongoDB
• Postgres

Quick start :

Prerequisites :

Docker & Docker compose

Getting started :

1. Run docker compose file

    cd ./deployment
    docker compose up -d

2. Once every containers are up and running, configure Elastic APM on Kibana by following instructions described here
3. Open Observability Workshop.sln using your favorite IDE (e.g Visual Studio or Rider)
4. Run both contained project in parallel.
