Event Listeners Inspector

View all registered event listeners across your application — organized by event class.

What It Shows

Field	Description
Event class	Fully qualified event class name
Listeners	List of listener classes/methods subscribed to this event
Groups	Common, Web, and Console event dispatchers (tab-separated)

Tabs

• Common — Event listeners shared across all contexts
• Web — Listeners specific to HTTP request handling
• Console — Listeners specific to CLI command execution

API Endpoints

Method	Path	Description
GET	/inspect/api/events	All event listeners by group

How It Works

The inspector reads the application's event dispatcher configuration and enumerates all registered listeners. For Symfony, this includes kernel events (kernel.request, kernel.response, etc.), Doctrine events, and custom application events.
