The MongoDB\Driver\Monitoring\LogSubscriber interface

(mongodb >=1.17.0)

Вступ

Classes implementing this interface may be registered as a subscriber and receive log messages from the extension. This is similar to stream-based debug logging (i.e. mongodb.debug) except that trace-level log messages are not received.

As with stream-based logging, it is only possible to register a logger globally using MongoDB\Driver\Monitoring\addSubscriber(). The extension is not able to distinguish log messages for individual MongoDB\Driver\Manager objects.

Попередньо визначені константи

MongoDB\Driver\Monitoring\LogSubscriber::LEVEL_ERROR: Error log level. An error condition that the extension is unable to report through its API. This is the most severe log level in the extension.
MongoDB\Driver\Monitoring\LogSubscriber::LEVEL_CRITICAL: Critical log level. An error condition with slightly less severity. This constant exists for consistency with libmongoc; however, the extension is unlikely to use it in practice.
MongoDB\Driver\Monitoring\LogSubscriber::LEVEL_WARNING: Warning log level. Indicates a situation where undesirable application behavior may occur.
MongoDB\Driver\Monitoring\LogSubscriber::LEVEL_MESSAGE: Message or notice log level. Indicates an event that is unusual but not problematic.
MongoDB\Driver\Monitoring\LogSubscriber::LEVEL_INFO: Info log level. High-level information about normal driver behavior.
MongoDB\Driver\Monitoring\LogSubscriber::LEVEL_DEBUG: Debug log level. Detailed information that may be helpful when debugging an application.
