Monolog Cascade integration to Magento 2

Installation

Add to your project's composer.json:

  "require": {
    "praxigento/mage2_ext_logging": "~0.1"
  }

Usage

Default configuration file is in var/log/logging.yaml (see src/etc/di.xml).

Get logger with ObjectManager:

public function __construct(
    \Psr\Log\LoggerInterface $logger,
    ...
) {
    $this->_logger = $logger;
    ...
}

Then log your messages:

$this->_logger->info("'Get account' operation is called.");
