Business metrics for starters

A VERY simple PHP, Prometheus & Grafana setup to get started with business metrics

Docker compose services

Assuming you have installed docker and docker-compose on your machine, go to the root directory of this project and run

docker-compose up -d

to fire up the following service setup.

1. nginx will provide three URLs:

2. http://127.0.0.1:8080 - The php script that provides metrics to the prometheus instance

3. http://127.0.0.1:9090 - The prometheus instance web frontend

4. http://127.0.0.1:3000 - The grafana instance web frontend

5. php will provide the PHP-FPM to run your PHP script under /public/metrics.php

6. prometheus will collect metrics from your PHP script unter http://127.0.0.1:8080/metrics.php

7. grafana will visualize metrics with the prometheus instance as its data source

Used libraries

• openmetrics-php/exposition-text to produce metrics in the OpenMetrics format that prometheus understands.
