Simple example to show implementation of observability in .NET 5
The basics of observability (Tracing, Metrics, Logging) and RabbitMq implementation made. While making these implementations, the following libraries used:
Tracing: OpenTelemetry's .NET libraries used.
Metrics: In OpenTelemetry, this part is still under development, so OpenTelemetry was not used. Instead, the prometheus-net library used.
Logging: Serilog and Seq used.
RabbitMq: RawRabbit library used because of its ease of implementation and middleware structure.
It simply creates a product in its database. Then the ProductCreated event is published to RabbitMq.
It simply creates a client in its database. It has also subscribed to the ProductCreated event. When this event comes, it saves a sample of the product in its database.
Open ObservabilityExample/compose directory and execute:
docker-compose -f external-apps-compose.yml up -d
It will run the required apps for observability. Then you can run the products and customers services together using:
docker-compose -f local-services.yml up -d
You can create a product using swagger at this link: http://localhost:5000/swagger/index.html
Then you can see traces using Jaeger at this link: http://localhost:16686/search
Example of showing traces using Jaeger
MetricsYou can see metrics using Grafana at this link: http://localhost:3010/login
If you don't want to use Grafana, you can also see metrics at this link: http://localhost:9090/
Then you can use the default username and password (admin) when logging into Grafana.
You can import pre-built dashboard for metrics if you want. Some of the pre-built dashboards:
You can see logs using Seq at this link: http://localhost:5341/#/events
- Add docker support
