This packag provides an Adapter implementation for endclothing/prometheus_client_php,
using Laravel's Eloquent to store metrics in your database. Is it a good idea? Probably not, but here it is anyway - maybe it'll fit your needs.
composer require rianfuro/laravel-prometheus-storage-adapter
php artisan migrate
There's no configuration attached to this library, the adapter will simply use your default connection from your database.php.
You can then simply register the adapter in your ServiceProvider, for example as follows:
$this->app->bind(Adapter::class, LaravelPrometheusStorageAdapter\EloquentStorageAdapter::class);
$this->app->singleton(CollectorRegistry::class);
