The MongoLog class

(Информация о версии неизвестна, возможно, только в SVN)

Введение

Logging can be used to get detailed information about what the driver is doing. With PHP-CLI, log output will be printed to stderr. Under an app server, log messages will generally be printed to an error log.

Logging is turned off, by default. This class allows you to turn on specific levels of logging for specific parts of the driver. Some examples:

<?php

// print every log message possible
MongoLog::setLevel(MongoLog::ALL); // all log levels
MongoLog::setModule(MongoLog::ALL); // all parts of the driver

// print significant events about replica set failover
MongoLog::setLevel(MongoLog::INFO);
MongoLog::setModule(MongoLog::RS);

// print info- and server tuning-level events from replica sets and connection pooling
MongoLog::setLevel(MongoLog::INFO|MongoLog::FINE);
MongoLog::setModule(MongoLog::RS|MongoLog::POOL);

?>

Предопределенные константы

MongoLog Constants

These constants can be used by both MongoLog::setLevel() and MongoLog::setModule().

MongoLog::NONE
Constant for turning logging off.
MongoLog::ALL
Constant for logging everything.

MongoLog Level Constants

These constants can be used by MongoLog::setLevel().

MongoLog::WARNING
This will print log messages about somewhat exceptional but not-quite-exception-worthy happenings.
MongoLog::INFO
Logs events that may be of interest to administrators, but are not particularly noteworthy.
MongoLog::FINE
Logs most events that the driver performs. Depending on the module being logged, this can be extremely noisy and is primarily for debugging.

MongoLog Module Constants

These constants can be used by MongoLog::setModule().

MongoLog::IO
Logs traffic to/from the database. Unless your program is trivial, this will create an enormous number of log messages.
MongoLog::PARSE
Log server string parsing.
MongoLog::POOL
Log connection pool activity. Creating new connections, reusing connections, and closing connections.
MongoLog::RS
Log replica set activity. Failovers, pinging, chosing secondaries to read from, etc.
MongoLog::SERVER
Log server status changes. Detecting primary, secondary and duplication detection.
