This project demonstrates a monitoring and observability setup for a PHP application. It includes various tools and services to monitor application performance, log analysis, and system metrics.

Disclaimer: This project is not production-ready and is intended solely for educational purposes to showcase how to build an observability and monitoring system.

The following services are included in this project:

• PHP: Runs the PHP application.
• Nginx: Serves the PHP application.
• PostgreSQL: Database for the application.
• Prometheus: Collects and stores metrics from the application and other services.
• Grafana: Visualizes metrics collected by Prometheus.
• Elasticsearch: Stores and indexes logs for analysis.
• Logstash: Processes and forwards logs to Elasticsearch.
• Kibana: Visualizes logs stored in Elasticsearch.

To set up the project, run the following commands:

make up
make stress-test

The stress-test/stress-test.sh script simulates traffic to the application by sending HTTP requests:

• 200 OK: Sent continuously.
• 404 Not Found: Sent every 10 successful requests.
• 500 Internal Server Error: Sent every 20 successful requests.

The stress-test/stress-test-500.sh script simulates traffic to the application by sending HTTP requests with a 500 error response.

This helps test the monitoring and logging setup under different conditions.

Once the setup is complete, you can access the services at the following URLs:

• PHP Application: http://localhost:8080/200
• Grafana: http://localhost:3000
• Prometheus: http://localhost:9090
• Kibana: http://localhost:5601
