How to get Magento 2 events/observers

October 19, 2015 - Magento 2

You can get the list of events/observers in Magento 2 in the \Magento\Framework\Event\Manager::dispatch() method. Since there is no access to the logger, you will have to add a logger instance in the constructor:

$protected $logger;
public function __construct(
   InvokerInterface $invoker,
   ConfigInterface $eventConfig,
   \Psr\Log\LoggerInterface $logger
)
{
   $this->_invoker = $invoker;
   $this->_eventConfig = $eventConfig;
   $this->logger = $logger;
}

$protected $logger;

public function __construct(

InvokerInterface $invoker,

ConfigInterface $eventConfig,

\Psr\Log\LoggerInterface $logger

)

{

$this->_invoker = $invoker;

$this->_eventConfig = $eventConfig;

$this->logger = $logger;

}

Now, call in the dispatch method:

$this->logger->info($message);

1	$this->logger->info($message);

Instead of info you can use \Psr\Log\LoggerInterface methods.
