A simple application instrumented with OTel for New Relic

Sample Java Application Instrumented with OpenTelemetry for New Relic

This repository contains a simple Java application to calculate the nth number (between 1-90) in the Fibonacci sequence. It has no front end and runs locally in a terminal window. The built in load generator will generate and error every 4th attempt as it attempts to calculate a number outside of 1-90 on these attempts.

The application in this exercise has been instrumented with OpenTelemetry. For similar versions of this same application, see the following repositories:

• No Instrumentation
• APM for New Relic

Requirements:

In order to participate in this exercise you will need...

• Laptop with Mac OS X, Windows is not supported for this workshop
• Docker for Mac
• A New Relic account

Step 1

Clone this repository to your local machine using git clone https://github.com/Bijesse/fibonacci-java-otel.git

Step 2

Navigate into the directory you just created and export your New Relic ingest license key using the command below. Note: be sure to update the command to include your ingest license key.

export NEW_RELIC_API_KEY=<your_license_key>

Step 3

Build and run the app using Docker:

docker-compose up

Step 4

Now that you have the application running on your device it is time to generate data for it. Open a new terminal tab, navigate to the proper directory (if necessary) and run the command below.

./load-generator.sh

Step 5

Head to your New Relic account to view the data coming in! The application named fibonacci-java should be found in under Services - OpenTelemetry in the left menu of the explorer page
