Logging

Logger can be used to capture internal logs to find and solve problems.
This library contains two default Logger implementions:

ConsoleLogger

A logger writes messages to console.
The example code to create it:

auto logger = cql::Logger::createConsole(cql::LogLevel::Debug);

Supported log levels:

• LogLevel::Emergency
• LogLevel::Alert
• LogLevel::Critical
• LogLevel::Error
• LogLevel::Warning
• LogLevel::Notice
• LogLevel::Info
• LogLevel::Debug

NoopLogger

A do-nothing logger.

auto logger = cql::Logger::createNoop();

Use logger

You can specify the logger in session configuration by calling SessionConfiguration::setLogger, for example:

auto configuration = cql::SessionConfiguration()
	.setMinPoolSize(1)
	.setMaxPoolSize(100)
	.setDefaultKeySpace("system")
	.setLogger(cql::Logger::createConsole(cql::LogLevel::Debug));
