README
Auto-instrument Symfony 6.4 LTS / 7.x apps for Daemon8. Requests, Doctrine queries, exceptions, Messenger, HTTP client, security events, and Monolog — captured automatically.
Tip
Help keep Daemon8 open source — star the main repo.
Install
composer require daemon8/symfony
daemon8 install # if you haven't already
Symfony Flex publishes config/packages/daemon8.yaml and registers the bundle. No Flex? Add Daemon8\Symfony\Daemon8Bundle::class => ['all' => true] to config/bundles.php.
Requires the Daemon8 daemon running locally. Without it, the bundle is a silent no-op.
Usage
Everything streams automatically after install. Emit manually by injecting Daemon8Client:
use Daemon8\Daemon8Client; final class CheckoutService { public function __construct(private readonly Daemon8Client $daemon8) {} public function process(Order $order): void { $this->daemon8->log('processing order #' . $order->id); $this->daemon8->send( ['event' => 'checkout', 'order_id' => $order->id], severity: 'info', channel: 'orders', ); } }
In dev mode, the WebProfiler toolbar shows a Daemon8 panel with every observation from the current request.
Configuration
DAEMON8_ENABLED=true DAEMON8_URL=http://127.0.0.1:9077/ingest DAEMON8_APP=checkout-api DAEMON8_TIMEOUT_MS=50
Per-subscriber toggles in config/packages/daemon8.yaml. Soft deps (Doctrine, Messenger, Mailer, etc.) are auto-detected — removing a package never crashes the bundle.
Respondents
React to observations in real time. Any service implementing Respondent is auto-tagged:
use Daemon8\Contracts\Respondent; use Daemon8\Filter; use Daemon8\Observation; use Daemon8\Severity; final class SlowQueryAnalyst implements Respondent { public function interest(): Filter { return new Filter(kinds: ['query'], severityMin: Severity::Warn); } public function respond(Observation $observation): void { // Full container access — Entity Manager, mailer, logger, anything. } }
Run the subscriber: bin/console daemon8:run
Requirements
- PHP 8.4+
- Symfony 6.4 LTS or 7.x
- Daemon8 daemon running locally
Development
composer install
composer check # phpstan + rector dry-run + phpcs + phpunit
