README

A native CakePHP 5.x plugin for Airbrake error tracking and exception monitoring. Automatically captures and reports exceptions, PHP errors, and log messages to Airbrake using API v3. This plugin does not depend on the legacy phpairbrake SDK.

No external dependencies - uses CakePHP's built-in HTTP client.

Features

• Native implementation using Airbrake API v3
• No phpairbrake SDK dependency
• Automatic exception and error tracking
• Seamless integration with CakePHP's error handling system
• Log engine for sending log messages to Airbrake
• Request context (URL, HTTP method, route, user agent, etc.)
• CakePHP route information (controller, action, prefix)
• User identification support (CakePHP Authentication plugin)
• Sensitive data filtering (passwords, tokens, etc.)
• Support for self-hosted Airbrake (Errbit)
• Environment-based configuration
• Zero external dependencies

Requirements

• PHP 8.1 or higher
• CakePHP 5.x
• Airbrake account (or self-hosted Errbit)

Installation

Install the plugin using Composer:

composer require salines/cakephp-airbrake

Migration from phpairbrake

If your application previously used the phpairbrake SDK, you can remove it from composer.json and keep the same Airbrake credentials. This plugin provides its own notifier (CakeAirbrake\Notifier) and sends notices directly using CakePHP's HTTP client.

Configuration

1. Load the Plugin

Add the plugin to your src/Application.php:

use CakeAirbrake\CakeAirbrakePlugin;

public function bootstrap(): void
{
    parent::bootstrap();

    $this->addPlugin(CakeAirbrakePlugin::class);
}

2. Configure Airbrake

Add the Airbrake configuration to your config/app.php:

'Airbrake' => [
    'projectId' => env('AIRBRAKE_PROJECT_ID'),
    'projectKey' => env('AIRBRAKE_PROJECT_KEY'),
    'environment' => env('APP_ENV', 'production'),
    'appVersion' => '1.0.0',
    'host' => 'https://api.airbrake.io', // Change for self-hosted
    'enabled' => true,
    'rootDirectory' => ROOT,
    'keysBlocklist' => [
        '/password/i',
        '/secret/i',
        '/token/i',
        '/authorization/i',
        '/api_key/i',
    ],
],

3. Configure Error Logger

To automatically send all exceptions and errors to Airbrake, configure the error logger in config/app.php:

'Error' => [
    'errorLevel' => E_ALL,
    'exceptionRenderer' => \Cake\Error\Renderer\WebExceptionRenderer::class,
    'skipLog' => [],
    'log' => true,
    'trace' => true,
    'logger' => \CakeAirbrake\Error\AirbrakeErrorLogger::class,
],

4. Configure Log Engine (Optional)

To send log messages to Airbrake, add the log engine configuration:

'Log' => [
    'airbrake' => [
        'className' => 'CakeAirbrake.Airbrake',
        'levels' => ['warning', 'error', 'critical', 'alert', 'emergency'],
    ],
],

The log engine automatically uses the global Airbrake configuration.

Environment Variables

You can configure the plugin using environment variables:

AIRBRAKE_PROJECT_ID=123456
AIRBRAKE_PROJECT_KEY=your-project-key
AIRBRAKE_HOST=https://api.airbrake.io
AIRBRAKE_ENABLED=true
APP_ENV=production

Usage

Automatic Error Tracking

Once configured with the error logger, all uncaught exceptions and PHP errors will automatically be sent to Airbrake.

Manual Exception Reporting

You can manually send exceptions to Airbrake:

use CakeAirbrake\Notifier;
use Cake\Core\Configure;

try {
    // Your code
} catch (\Exception $e) {
    $notifier = new Notifier(Configure::read('Airbrake'));
    $notifier->notify($e);
}

Using the Log Engine

Send log messages to Airbrake:

use Cake\Log\Log;

Log::error('Something went wrong', ['scope' => 'airbrake']);
Log::critical('Database connection failed');

// With exception context
Log::error('Operation failed', [
    'exception' => $e,
    'user_id' => 123,
]);

Adding Custom Context

You can add custom context to your error reports using filters:

use CakeAirbrake\Notifier;
use Cake\Core\Configure;

$notifier = new Notifier(Configure::read('Airbrake'));

$notifier->addFilter(function ($notice) {
    $notice['context']['customField'] = 'customValue';
    $notice['params']['orderId'] = 12345;
    return $notice;
});

$notifier->notify($exception);

Filtering Notices

You can prevent certain notices from being sent by returning null from a filter:

$notifier->addFilter(function ($notice) {
    // Don't send 404 errors
    if (str_contains($notice['errors'][0]['type'], 'NotFoundException')) {
        return null;
    }
    return $notice;
});

Setting Severity

You can set the severity level for notices:

$notifier = new Notifier(Configure::read('Airbrake'));
$notice = $notifier->buildNotice($exception);
$notice['context']['severity'] = 'critical'; // debug, info, notice, warning, error, critical
$notifier->sendNotice($notice);

Testing With webhook.site

You can test delivery without a real Airbrake project by sending notices to a webhook.site URL.

1. Create a new endpoint at https://webhook.site and copy the unique URL.
2. Configure a custom notices URL:

'Airbrake' => [
    'projectId' => 1,
    'projectKey' => 'test-key',
    'customNoticesUrl' => 'https://webhook.site/your-unique-id',
],

1. Trigger a test notice:

use CakeAirbrake\Notifier;
use Cake\Core\Configure;

$notifier = new Notifier(Configure::read('Airbrake'));
$notifier->notify(new \RuntimeException('Webhook test notice'));

Open the webhook.site page to inspect the JSON payload.

Configuration Options

Self-Hosted Airbrake (Errbit)

To use with a self-hosted Airbrake server like Errbit:

'Airbrake' => [
    'projectId' => 1,
    'projectKey' => 'your-api-key',
    'host' => 'https://your-errbit-server.com',
    // ... other options
],

Filtering Sensitive Data

The plugin automatically filters sensitive data based on the keysBlocklist configuration. By default, it filters keys matching:

• /password/i
• /secret/i
• /token/i
• /authorization/i
• /api_key/i
• /apikey/i
• /access_token/i

You can add your own patterns:

'keysBlocklist' => [
    '/password/i',
    '/secret/i',
    '/credit_card/i',
    '/ssn/i',
    '/cvv/i',
],

Disabling in Development

You can disable Airbrake in development:

'Airbrake' => [
    // ... other config
    'enabled' => !Configure::read('debug'),
],

Or using environment variables:

AIRBRAKE_ENABLED=false

Notice Structure

The plugin sends notices to Airbrake in the following structure (API v3):

{
  "errors": [{
    "type": "RuntimeException",
    "message": "Something went wrong",
    "backtrace": [...]
  }],
  "context": {
    "notifier": {"name": "cakephp-airbrake", "version": "1.0.0"},
    "environment": "production",
    "hostname": "server-01",
    "os": "Linux",
    "language": "PHP 8.1.0",
    "severity": "error",
    "url": "https://example.com/users/123",
    "httpMethod": "GET",
    "route": "/Users/view",
    "component": "Users",
    "action": "view",
    "user": {"id": 1, "name": "John", "email": "john@example.com"}
  },
  "environment": {...},
  "params": {...},
  "session": {...}
}
