elastic-apm-test

A dumb project to test the whole Elastic stack including APM solution using Docker.

Sample application

Java

The project is written and compiled with Java 11.

Build

It uses a Gradle wrapper to build the app.

To build the project, simply run:

./gradlew build

Endpoints

It describes the base pathes of the application. By default, the application runs on port 8080.

Get all foos

/foos

Get a single foo

/foos/{a-foo-id}

Get all users

/users

This endpoint is secured and require an authorization header. The user is user and its password is ekino.

You can add the header Authorization with value Basic dXNlcjpla2lubw==.

The Elastic stack

Docker

The whole stack is based on Docker and it uses the docker-compose.yml to manage it.

N.B. The Java application must have been built before because its JAR is included in a Docker image.

To build and deploy the whole stack, run:

docker-compose -f docker-compose.yml up -d

Accessing the components

The interesting part here is the Kibana application to view the APM metrics and logs.

It is accessible here: http://localhost:5601/app/kibana

The other components: APM server: http://localhost:8200 Elasticsearch: http://localhost:9200 Logstash: http://localhost:9600

Adding a bit of volumetry

In order to have a bit of date without spamming the endpoints on my own ; I used JMeter.

The profile I used is jmeter-profile.jmx.

You can find more information on JMeter here.
