This project is an Azure distribution of the OpenTelemetry Spring Boot starter.

It allows you to get telemetry data on Azure with a Spring Boot native image application.

For a Spring Boot application running on a JVM runtime (not with a GraalVM native image), we recommend using the Application Insights Java agent.

Add the Spring Cloud Azure Starter Monitor dependency.

Instruction for Spring Boot native image applications.

All the features described in the OpenTelemetry Spring Boot starter documentation work with Azure Monitor OpenTelemetry Distro / Application Insights in Spring Boot native image Java application.

You have just to replace the opentelemetry-spring-boot-starter dependency by the spring-cloud-azure-starter-monitor one.

In order to export telemetry data to Azure Monitor, you will need the connection string to your Application Insights resource. Go to Azure Portal, search for your resource. On the overview page of your resource, you will find the connection string in the top right corner.

You can then configure the connection string in two different ways:

• With the APPLICATIONINSIGHTS_CONNECTION_STRING environment variable
• With the applicationinsights.connection.string system property. You can use -Dapplicationinsights.connection.string or add the property to your application.properties file.

The Application Map uses the cloud role name to identify components on the map.

You can set the cloud role name with the spring.application.name property. You have other options to set the cloud role role: see how to set the service name in the OpenTelemetry documentation.

At this step, you can build your Spring Boot native image application and start it:

mvn -Pnative spring-boot:build-image
docker run -e APPLICATIONINSIGHTS_CONNECTION_STRING="{CONNECTION_STRING}" {image-name} 

where you have to replace {CONNECTION_STRING} and {image-name} by your connection string and the native image name.

You can disable the monitoring by setting the otel.sdk.disabled property or the OTEL_SDK_DISABLED environment variable to true.
