How to hook into action/filter call

The callbacks hooked onto ‘all’ are called prior to the callbacks for any hook (action and filters) being called. (See source)

add_action( 'all', 'wpse115617_all_hooks' );

function wpse115617_all_hooks(){
   //This is called for every filter & action

   //You can get the current hook to which it belongs with:
   $hook = current_filter();

}
