This repository demonstrates Observability in springboot microservices using Azure Application Insights Java SDK.

• Order Creation Microservice (Producer Service)- Springboot microservice responsible for creating new orders and pushing events to RabbitMQ.
• Postgres SQL for persistence.
• Rabbit MQ - Message Broker to enable asynchronous communication.
• Order Logging Service (consumer service) - Springboot microservice which reacts on the events published by Order creation service and logs the information to console.

• Create an application insights resource and obtain the instrumentation key. You can follow this tutorial for details.
• modify the application.properties for OrderCreationService and OrderLoggingService and add update the property azure.application-insights.instrumentation-key=<your-ikey> with your instrumentation key.

mvnw clean build

This command will build all the microservices.

Prerequisites:

• Make sure you have docker installed and running locally. You can install docker by following the steps on docker's official website.

run the command docker-compose up. This will deploy all the microservices including RabbitMQ message broker on a common docker network.

curl -d '{"productId" : "car123", "productName" : "car"}' -H "Content-Type: application/json" -X POST http://localhost:18080/orders

This would create a new order message and publish it to RabbitMQ. The consumer service reacts on this message, and logs the information on console.
