📖 About

This is a collection of small and focused instances, each of which covers a single and defined approach to Java application development and an required technologies implementation. This project presents instances of how to collect and display statistics on the use of micro-services and their logs, as well as distributed request tracing. A strong focus of these instances is the different cases of the micro-services distributed tracing, micro-services logs collecting and analytics and interactive visualization web application realizations.

🎚 Features

The project with instances of:

  • the micro-services distributed tracing technology implementation via Jaeger
  • the micro-services logs collecting technology implementation via loki & promtail
  • the analytics and interactive visualization web application technology implementation via Graphana & Prometheus

🚦 Getting Started

These instructions allow to get a copy of this project and run it on a local machine.

Prerequisites

Before using it, make sure that follows software are installed on the local machine:

Using

To run and try out each instance is required to:

  1. Launch containers with services

To do the launching some incstance, go to the instance directory and execute the following command:

docker-compose up --build
  1. Open sevices GUI

When all services will start, you could open your browser and go to the services endpoints:

  • Graphana endpont (user admin, password admin):
http://localhost:3000/
  • Jaeger endpont:
http://localhost:16686/
  • Prometheus endpont:
http://localhost:9090/
  • PostgreSQL Exporter endpont:
http://localhost:9187/
  • Some Api Client endpoint (with specs):
http://localhost:8082/swagger-ui.html
  • Some Api endpoint (with specs):
http://localhost:8081/swagger-ui.html
  1. [OPTIONAL] Send requests to instance service. Because the some-api-executing ervice will do the requests to some-api-client automatically every 30 seconds.

Launching

To do the launching some incstance, go to the instance directory and execute the following command:

docker-compose up --build
