Installation

You may install the package via composer:

composer require directorytree/metrics

Then, publish the migrations:

php artisan vendor:publish --tag="metrics-migrations"

Finally, run the migrations:

php artisan migrate

Setup

Optionally, you may publish the configuration file:

php artisan vendor:publish --tag="metrics-config"

This will create a config/metrics.php file where you may configure the driver and queueing behavior.

Using the Redis Driver

For distributed applications or high-traffic scenarios, you may use the redis driver to store captured metrics in Redis before committing them to the database in batches.

First, set the driver to redis in your configuration:

// config/metrics.php

return [
    'driver' => 'redis',
    
    // ...
];

Or via environment variable:

METRICS_DRIVER=redis

Then, you may schedule the metrics:commit command to periodically commit metrics from Redis to your database:

Important

Remember to disable auto_commit in the configuration file if you plan on committing metrics using the commit command.

// app/Console/Kernel.php

protected function schedule(Schedule $schedule): void
{
    $schedule->command('metrics:commit')->hourly();
}

You may also run the command manually:

php artisan metrics:commit

This approach provides reduced database load since metrics can be committed in bulk at an expected interval instead of at the end of the request life-cycle.

The Redis driver uses a hash to store pending metrics with a configurable TTL (default of 1 day). This ensures metrics are eventually committed even if the scheduled command fails temporarily.

Usage

Recording Metrics

Record a metric using the Metrics facade:

use DirectoryTree\Metrics\MetricData;
use DirectoryTree\Metrics\Facades\Metrics;

Metrics::record(new MetricData('signups'));

Or using the metric global helper:

metric('signups')->record();

Or using the PendingMetric class:

use DirectoryTree\Metrics\PendingMetric;

PendingMetric::make('signups')->record();

Which ever method you use, metrics are recorded in the same way. Use whichever you prefer.

For the rest of the documentation, we will use the metric helper for consistency and brevity.

Metric Values

By default, metrics have a value of 1. You may specify a custom value in the record method:

// Track multiple API calls at once
metric('api:requests')->record(10);

// Track batch job completions
metric('jobs:completed')->record(250);

If you record the same metric multiple times, the values will be summed:

metric('auth:logins')->record(); // value: 1
metric('auth:logins')->record(); // value: 1

// Database will contain one metric with value: 2

Recording with Categories

Organize metrics into categories:

// Track API calls by endpoint
metric('api:requests')->category('users')->record();
metric('api:requests')->category('orders')->record();

// Track errors by severity
metric('app:errors')->category('critical')->record();
metric('app:errors')->category('warning')->record();

// Track purchases by payment method
metric('purchases')->category('stripe')->record();
metric('purchases')->category('paypal')->record();

These will be stored as separate metrics, allowing you to track the same metric across different contexts.

Recording with Dates

By default, metrics are recorded with today's date. You may specify a custom date using the date method:

use Carbon\Carbon;

// Backfill signup data from an import
metric('signups')
    ->date(Carbon::parse('2025-01-15'))
    ->record(50);

// Record yesterday's batch job completions
metric('jobs:completed')
    ->date(Carbon::yesterday())
    ->record(1250);

Recording for Models

Associate metrics with Eloquent models using the HasMetrics trait:

use DirectoryTree\Metrics\HasMetrics;
use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    use HasMetrics;
}

Then record metrics for a specific model:

// Track logins per user
metric('auth:logins')
    ->measurable(Auth::user())
    ->record();

// Track orders per customer
metric('orders')
    ->measurable(Customer::find(...))
    ->record();

// Track API calls per client
metric('api:requests')
    ->measurable(ApiClient::find(...))
    ->record();

Query metrics for a model:

// Get total logins for a user
$totalLogins = $user->metrics()
    ->where('name', 'auth:logins')
    ->sum('value');

// Get orders this month for a customer
$ordersThisMonth = $customer->metrics()
    ->where('name', 'orders')
    ->thisMonth()
    ->sum('value');

Recording with Custom Attributes

Store additional context with your metrics by adding custom attributes. This is useful for segmenting metrics by various dimensions like source, country, device type, or any other custom data.

First, create a migration to add custom columns to the metrics table:

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

Schema::table('metrics', function (Blueprint $table) {
    $table->string('source')->nullable()->index();
    $table->string('country')->nullable()->index();
    $table->string('device')->nullable();
});

Then, use the with() method to record metrics with custom attributes:

// Track page views with traffic source
metric('page_views')
    ->with(['source' => 'google'])
    ->record();

// Track conversions with multiple attributes
metric('conversions')
    ->with([
        'source' => 'facebook',
        'country' => 'US',
        'device' => 'mobile',
    ])
    ->record();

// Combine with other methods
metric('api:requests')
    ->category('users')
    ->with(['client_id' => 'abc123'])
    ->record();

Custom attributes are included in the metric's uniqueness check, meaning metrics with different attribute values are stored separately:

metric('page_views')->with(['source' => 'google'])->record();   // Creates metric #1
metric('page_views')->with(['source' => 'facebook'])->record(); // Creates metric #2
metric('page_views')->with(['source' => 'google'])->record();   // Increments metric #1

This allows you to segment and analyze metrics by any dimension:

// Get page views by source
$googleViews = Metric::where('name', 'page_views')
    ->where('source', 'google')
    ->sum('value');

// Get conversions by country this month
$conversions = Metric::thisMonth()
    ->where('name', 'conversions')
    ->get()
    ->groupBy('country')
    ->map->sum('value');

// Get mobile vs desktop traffic
$mobileViews = Metric::today()
    ->where('name', 'page_views')
    ->where('device', 'mobile')
    ->sum('value');

You can also use custom attributes with the MetricData class:

use DirectoryTree\Metrics\MetricData;
use DirectoryTree\Metrics\Facades\Metrics;

Metrics::record(new MetricData(
    name: 'page_views',
    additional: [
        'source' => 'google',
        'country' => 'US',
    ]
));

Or with the PendingMetric class:

use DirectoryTree\Metrics\PendingMetric;

PendingMetric::make('page_views')
    ->with(['source' => 'google', 'country' => 'US'])
    ->record();

Important

Core metric attributes (name, category, year, month, day, measurable_type, measurable_id, value) cannot be overridden via custom attributes. They are protected and will always use the values set through their respective methods.

Capturing & Committing

For high-performance scenarios, you may capture metrics in memory and commit them in batches:

use DirectoryTree\Metrics\Facades\Metrics;

Metrics::capture();

// Record multiple metrics...
metric('signups')->record();
metric('notifications:sent')->category('welcome')->record();
metric('signups')->record();

// Commit all captured metrics at once
Metrics::commit();

Captured metrics are automatically committed when the application terminates. You may also stop capturing manually:

Metrics::stopCapturing();

To enable capturing for your entire application, start capturing in your AppServiceProvider:

// app/Providers/AppServiceProvider.php

use DirectoryTree\Metrics\Facades\Metrics;

class AppServiceProvider extends ServiceProvider
{
    // ...

    public function boot(): void
    {
        Metrics::capture();
    }
}

This will batch all metrics recorded during the request and commit them automatically when the application terminates, reducing database queries and improving performance.

Example: High-Traffic Controller

public function store(Request $request)
{
    Metrics::capture();

    // Process multiple operations
    $user = User::create($request->validated());
    metric('signups')->record();

    $user->sendWelcomeEmail();
    metric('notifications:sent')->category('welcome')->record();

    event(new UserRegistered($user));
    metric('events:dispatched')->record();

    // All metrics committed automatically at end of request
    return response()->json($user);
}

Example: Batch Job Processing

public function handle()
{
    Metrics::capture();

    Order::pending()->each(function (Order $order) {
        $order->process();

        metric('orders:processed')->record();
    });

    Metrics::commit(); // Batch commit all metrics
}

Querying Metrics

The Metric model includes a powerful query builder with date filtering methods:

use DirectoryTree\Metrics\Metric;

// Get today's metrics
$metrics = Metric::today()->get();

// Get this week's metrics
$metrics = Metric::thisWeek()->get();

// Get this month's metrics
$metrics = Metric::thisMonth()->get();

// Get this year's metrics
$metrics = Metric::thisYear()->get();

// Get yesterday's metrics
$metrics = Metric::yesterday()->get();

// Get last week's metrics
$metrics = Metric::lastWeek()->get();

// Get last month's metrics
$metrics = Metric::lastMonth()->get();

// Get last year's metrics
$metrics = Metric::lastYear()->get();

// Get metrics between specific dates
$metrics = Metric::betweenDates(
    Carbon::parse('2025-01-01'),
    Carbon::parse('2025-12-31')
)->get();

// Get metrics on a specific date
$metrics = Metric::onDate(Carbon::parse('2025-10-15'))->get();

Chain with standard Eloquent methods:

// Get today's signups
$signups = Metric::today()
    ->where('name', 'signups')
    ->sum('value');

// Get this week's purchases
$purchases = Metric::thisWeek()
    ->where('name', 'purchases')
    ->sum('value');

// Get API usage by endpoint this month
$apiUsage = Metric::thisMonth()
    ->where('name', 'api:requests')
    ->get()
    ->groupBy('category')
    ->map->sum('value');

// Count unique metrics recorded today
$count = Metric::today()->count();

Example: Compare Growth

// Compare this month vs last month signups
$thisMonth = Metric::thisMonth()
    ->where('name', 'signups')
    ->sum('value');

$lastMonth = Metric::lastMonth()
    ->where('name', 'signups')
    ->sum('value');

$growth = (($thisMonth - $lastMonth) / $lastMonth) * 100;

Example: Calculate Error Rate

// Get error rate for the year
$errors = Metric::thisYear()
    ->where('name', 'errors')
    ->sum('value');

$requests = Metric::thisYear()
    ->where('name', 'api:requests')
    ->sum('value');

$errorRate = ($errors / $requests) * 100;

Testing

Metrics includes a fake implementation for testing:

use DirectoryTree\Metrics\Measurable;
use DirectoryTree\Metrics\Facades\Metrics;

public function test_user_signup_records_metric()
{
    Metrics::fake();

    // Your code that records metrics...
    $this->post('register', [
        'email' => '[email protected]',
        'password' => 'password',
    ]);

    // Assert metrics were recorded
    Metrics::assertRecorded('signups');
}

public function test_api_call_records_metric_with_endpoint()
{
    Metrics::fake();

    $this->getJson('api/users');

    // Assert metrics were recorded with a closure
    Metrics::assertRecorded(fn (Measurable $metric) =>
        $metric->name() === 'api:requests' &&
        $metric->category() === 'users'
    );
}

public function test_failed_login_records_metric()
{
    Metrics::fake();

    $this->post('login', [
        'email' => '[email protected]',
        'password' => 'wrong',
    ]);

    // Assert metrics were not recorded
    Metrics::assertNotRecorded('auth:logins');

    // Assert failed login was recorded
    Metrics::assertRecorded('auth:attempts');
}

public function test_purchase_records_metric_for_user()
{
    Metrics::fake();

    $user = User::factory()->create();

    $this->actingAs($user)->post('purchases', [
        'product_id' => 1,
    ]);

    // Assert metrics were recorded with model
    Metrics::assertRecorded(fn ($metric) =>
        $metric->name() === 'purchases' &&
        $metric->measurable()?->is($user)
    );
}

public function test_batch_job_records_metrics()
{
    Metrics::fake();

    // Run your batch job
    Artisan::call('orders:process');

    // Assert metrics were recorded a specific number of times
    Metrics::assertRecordedTimes('orders:processed', 100);
}

Access recorded metrics in tests:

Metrics::fake();

metric('api:requests')->category('users')->record();

// Get all recorded metrics
$all = Metrics::recorded();

// Get metrics by name
$apiCalls = Metrics::recorded('api:requests');

// Get metrics with a closure
$userEndpoint = Metrics::recorded(fn ($metric) =>
    $metric->category() === 'users'
);

Extending & Customizing

Custom Metric Manager

Create your own metric manager by implementing the MetricManager interface:

namespace App\Metrics;

use DirectoryTree\Metrics\Measurable;
use DirectoryTree\Metrics\MetricManager;

class CustomMetricManager implements MetricManager
{
    public function record(Measurable $metric): void
    {
        // Your custom recording logic...
    }

    public function commit(): void
    {
        // Your custom commit logic...
    }

    public function capture(): void
    {
        // Your custom capture logic...
    }

    public function isCapturing(): bool
    {
        // Your custom capturing check...
    }

    public function stopCapturing(): void
    {
        // Your custom stop capturing logic...
    }
}

Then bind it in your AppServiceProvider:

use App\Metrics\CustomMetricManager;
use DirectoryTree\Metrics\MetricManager;

public function register(): void
{
    $this->app->singleton(MetricManager::class, CustomMetricManager::class);
}

Custom Metric Repository

Create a custom repository for storing captured metrics:

namespace App\Metrics;

use DirectoryTree\Metrics\Measurable;
use DirectoryTree\Metrics\MetricRepository;

class CustomMetricRepository implements MetricRepository
{
    public function add(Measurable $metric): void
    {
        // Your custom add logic...
    }

    public function all(): array
    {
        // Your custom retrieval logic...
    }

    public function flush(): void
    {
        // Your custom flush logic...
    }
}

Then bind it in your AppServiceProvider:

use App\Metrics\CustomMetricRepository;
use DirectoryTree\Metrics\MetricRepository;

public function register(): void
{
    $this->app->singleton(MetricRepository::class, CustomMetricRepository::class);
}
