• 🧠 Thread Optimization Advisor - Smart analysis of your Go goroutines and memory usage
• 🎚️ Interactive Simulator - Test different safety margins to find your ideal num_threads setting
• 🎨 Premium UI - Modern, status-reactive dashboard with distinct "System Optimal", "Can Scale", and "Caution" states
• 📈 Core Metrics - Request counts, response sizes, goroutines, memory, and total responses
• 🔧 Easy Installation - Interactive CLI installer for systemd (Linux) and launchd (macOS)
• 🗑️ Data Management - Built-in commands for pruning data and clearing the entire metrics history
• 🧪 Full Test Suite - Comprehensive Pest tests for advisor logic and data generation

Requirements

• PHP 8.1+
• Laravel 10, 11, or 12
• Livewire 3.x
• Caddy server with metrics enabled (servers { metrics } in Caddyfile)
• SQLite support

Installation

1. Install the package

composer require iperamuna/laravel-caddy-metrics

2. Publish configurations and assets

# Configuration
php artisan vendor:publish --tag=caddy-metrics-config

# Collector Binary
php artisan vendor:publish --tag=caddy-metrics-binary

# Dashboard Views (Optional for customization)
php artisan vendor:publish --tag=caddy-metrics-views

3. Install the collector service

The installer handles everything for you:

• Installs the Go collector binary
• Creates the systemd (Linux) or launchd (macOS) service
• Publishes the CaddyMetricsServiceProvider for access control
• Registers the provider in bootstrap/providers.php

# Linux (requires sudo)
sudo php artisan caddy-metrics:install

# macOS
php artisan caddy-metrics:install

3a. Configure Remote Servers

On remote servers where you cannot run the full installer or need to manage settings via environment variables, use the configuration command:

php artisan caddy-metrics:configure

This interactive command will help you set up your .env file with the correct ports, URLs, and paths for Caddy metrics. You can run it with --no-interaction in deployment scripts as long as your environment variables are already set.

4. Dashboard Authorization

To control who can access the Caddy Metrics dashboard in production, you must configure the viewCaddyMetrics gate in your app/Providers/CaddyMetricsServiceProvider.php file (created during installation).

/**
 * Register the Caddy Metrics gate.
 *
 * This gate determines who can access Caddy Metrics in non-local environments.
 *
 * @return void
 */
protected function gate()
{
    Gate::define('viewCaddyMetrics', function ($user) {
        return in_array($user->email, [
            'taylor@laravel.com',
        ]);
    });
}

By default, the dashboard is only accessible in the local environment.

Configuration

Edit config/caddy-metrics.php to match your environment:

return [
    'enabled' => env('CADDY_METRICS_ENABLED', true),
    'dashboard_url' => env('CADDY_METRICS_DASHBOARD_URL', '/caddy/metrics'),
    'frankenphp_threads' => env('FRANKENPHP_THREADS', 12),
    'caddyfile_path' => env('CADDYFILE_PATH', '/etc/frankenphp/Caddyfile'),
    'retention_days' => env('CADDY_METRICS_RETENTION_DAYS', 7),
];

Thread Optimization Advisor

The dashboard includes a dedicated Thread Advisor that analyzes your server's average and peak loads.

• Interactive Simulation: Adjust the Safety Margin Slider to see exactly how many threads you should allocate to maintain your desired headroom.
• Can Scale Branding: Identifies when your server has "headroom" to scale up for better performance.
• Caddyfile Recommendations: provides copy-and-paste snippets for your Caddyfile based on simulation results.

Commands

Service Management Examples

# Check if the collector is running
sudo php artisan caddy-metrics:maintain status

# Restart the service after config changes
sudo php artisan caddy-metrics:maintain restart

# Stop the collector
sudo php artisan caddy-metrics:maintain stop

Testing

The package includes a robust test suite using Pest.
