Logging NodeJS with the ELK Stack

This repo serves as a functioning proof-of-concept for the video Logging Nodejs apps with ELK: Elasticsearch, Logstash, and Kibana.

Requirements

You'll need docker desktop to run the example.

Usage

Launch the environment

Type make up to bring the docker-compose environment up. This will launch the ExpressJS application server, Elasticsearch, Logstash, and Kibana.

Seeding the database environment

Use make migrate to create the database schema (required for the /users endpoint) followed by make seed to populate the database with test data.

Generate some logs

Once the environment is running, hit http://localhost:3000 and http://localhost:3000/users to generate some logs.

The logs are sent to logstash using the winston-logstash-transport in ./helpers/logging.js. Logstash is configured to send the logs to Elasticsearch using the config found in elastic/logging.conf.

Launch Kibana and follow the instructions to setup the logstash index pattern. You can then view the logs using Kibana Discovery.

The ExpressJS / endpoint simply logs an info message. The /users endpoint logs an info message but also some key/value pairs that can be visualized in Kibana (and optionally reported/monitored/put on a dashboard/etc...)

Happy coding!
