Laravel Prometheus demo app

This repo contains a demo app for Laravel Prometheus.

You'll find more info on how to use this app in this blog post.

The demo application is vanilla Laravel app with:

• Laravel Prometheus installed
• Laravel Horizon installed with 4 queues configured
• An artisan command app:dispatch-jobs to dispatch dummy jobs

Clone this repo and run composer install.

You should install the Grafana agent via brew and not start it as a daemon (we'll start it manually later on).

The agent config should be saved at /opt/homebrew/etc/grafana-agent/config.yml
