I have dirty solution (in \Zend\EventManager\EventManager):

class EventManager implements EventManagerInterface
{
    // ...
    public static $allEvents = [];
    // ...
    public function attach($event, $callback = null, $priority = 1)
    {
        // ...
        if (empty($this->events[$event])) {
            $this->events[$event] = new PriorityQueue();
            self::$allEvents[$event] = new PriorityQueue();
        }

        // ...

        $this->events[$event]->insert($listener, $priority);
        self::$allEvents[$event]->insert($listener, $priority);
        return $listener;
    }

after this i see all :) but this is unacceptable and very dirty.

@froschdesign
no, this not work, because some services have own EventManager:

$this->setEventManager(new EventManager());
// or
$this->events = new EventManager();

in my task i need get all (ALL in whole app) events and handlers.

Now i have problem: I have big application with many modules, and when i see in code $this->getEventManager()->trigger($event); i have no idea what will be executed. I investigate this and spend many time with Crtl+F in whole project.

I want solve this faster if i have map: events=>callbacks+priorities, like this:

@froschdesign He's asking about v2, not v3.

@maxgu — The following methods will assist:

• EventManager::getEvents() returns a list of all events currently registered.
• EventManager::getListeners($event) returns a list of all CallbackHandlers associated with a given event. Caveat: it only returns those directly attached to the EM instance. You can use $handler->getMetadatum('priority') to get the priority at which the given handler is attached.
• EventManager::getIdentifiers() will return the list of identifiers the EM instance exposes and will look for shared listeners on.
• EventManager::getSharedManager() will return the shared event manager instance.
• SharedEventManager::getEvents() will return a list of all events with shared listeners, across all EM instances; likely, if you're only looking for listeners for a single EM instance, you won't need this.
• SharedEventManager::getListeners($id, $event) returns a list of CallbackHandlers representing the shared listeners for the given identifier.

Hopefully with the above information, you can stitch something together!

@snapshotpl thnx, but ZfSnapEventDebugger show ONLY triggered on current URI events, it not show (for examlpe):

dispatch.error
    Zend\Mvc\View\Http\RouteNotFoundStrategy::detectNotFoundError 1
    Zend\Mvc\View\Http\RouteNotFoundStrategy::prepareNotFoundViewModel 1
    Zend\Mvc\View\Http\ExceptionStrategy::prepareExceptionViewModel 1
    Zend\Mvc\View\Http\InjectViewModelListener::injectViewModel -100
