How-To-Run

inspectit-ocelot

Start the configuration-server via java -jar inspectit-ocelot-configurationserver-2.6.6.jar. You can reach the UI on port 8090.

Start the EUM-server via java -jar inspectit-ocelot-eum-server.2.6.2.jar The server should automatically apply the application.yml, which enables the influx-exporter for metrics and the OTLP-exporter for traces. The EUM-server also provides the boomerang-opentelemetry-plugin.

To start the ocelot-agent please view the demo-section.

Docker

Start the docker container via docker compose up in the /docker folder. You can open the UI of some containers on the following ports:

• Jaeger: 16686
• Grafana: 3030

Demo

You can start the demo application without an attached ocelot agent just like every other spring application.

To start the application with an attached ocelot agent, you have to:

• build a demo.jar via gradle assemble
• start the demo via java -javaagent:"<absolute-path-to-your-project>\inspectit-ocelot-dev-demo\inspectit-ocelot\inspectit-ocelot-agent-2.6.6.jar" -Dinspectit.service-name=my-demo-agent -Dinspectit.config.http.url=http://localhost:8090/api/v1/agent/configuration -jar <absolute-path-to-your-project>\inspectit-ocelot-dev-demo\build\libs\com.example.demo-0.0.1-SNAPSHOT.jar

You can reach the main-page at http://localhost:8081

To collect traces, open the http://localhost:8081/greeting. This page does load the boomerang-opentelemetry-plugin, collects traces and sends them to the EUM-server. You can also create traces by clicking on the 'Change picture' button. This button should change the colour of the displayed ocelot.

If you experience a lacking web-UI, please ensure to install all node_modules for the frontend. You can install the node_modules via: yarn install --modules-folder src/main/resources/static in the /demo folder. Please ensure you have installed yarn.
