The MongoDB\Driver\Monitoring\CommandSubscriber interface

(mongodb >=1.3.0)

Introduction

Classes may implement this interface to register an event subscriber that is notified for each started, successful, and failed command event. See Application Performance Monitoring (APM) for additional information.

Interface synopsis

class MongoDB\Driver\Monitoring\CommandSubscriber implements MongoDB\Driver\Monitoring\Subscriber {
/* Methods */

Changelog

Version Description
PECL mongodb 1.15.0 Return types for methods are declared as tentative on PHP 8.0 and newer, triggering deprecation notices in code that implements this interface without declaring the appropriate return types. The #[ReturnTypeWillChange] attribute can be added to silence the deprecation notice.
