Tanzu Observability OTel demo app

This is a sample application using Spring Boot with Jersey called beachshirts, which makes shirts for the beach.

Running the application

1. git clone this repo and navigate to this dir:

   git clone https://github.com/wavefrontHQ/otel-demo-app-java
   cd otel-demo-app-java

2. Run mvn clean install from the root directory of the project.

3. Using the following commands from the root directory, run all the services:

   java -jar ./shopping/target/shopping-1.0-SNAPSHOT.jar
   java -jar ./styling/target/styling-1.0-SNAPSHOT.jar
   java -jar ./delivery/target/delivery-1.0-SNAPSHOT.jar

4. View the shopping menus:

   curl http://localhost:50050/shop/menu

5. Order shirts using HTTP POST request:

   curl http://localhost:50050/shop/order -d '{"styleName": "testStyle1", "quantity": 5}'

   • You can use ./loadgen.sh [interval] in the root directory to send a request ordering random shirts every interval seconds (defaults to every 1 second)

Adding OpenTelemetry auto-instrumentation

1. Download the OpenTelemetry Java Agent:

   curl -Lo /tmp/opentelemetry-javaagent.jar https://github.com/open-telemetry/opentelemetry-java-instrumentation/releases/latest/download/opentelemetry-javaagent.jar

2. Run the services, attaching the agent:

   JAVA_AGENT=/tmp/opentelemetry-javaagent.jar
   java -jar -javaagent:$JAVA_AGENT ./shopping/target/shopping-1.0-SNAPSHOT.jar
   java -jar -javaagent:$JAVA_AGENT ./styling/target/styling-1.0-SNAPSHOT.jar
   java -jar -javaagent:$JAVA_AGENT ./delivery/target/delivery-1.0-SNAPSHOT.jar

3. Run the OpenTelemetry Collector with the tanzuobservability exporter configured to point at your wavefront-proxy.

4. Run the wavefront-proxy with a token and server pointing to your Tanzu Observability endpoint.

5. Order some shirts and see traces appear in the Tanzu Observability UI.
