Logging in Magento 2.4+

Magento, one of the most powerful eCommerce platforms, constantly evolves to meet the demands of developers and users alike. With the release of Magento 2.4.3, there were significant changes that developers needed to be aware of. One such change was the removal of the Laminas-log module, which has been a long-time tool for logging purposes in Magento 2.

This update has led to a shift in how logging is handled within Magento 2. Before version 2.4.3, developers would use Laminas-log to log messages for debugging, error handling, and custom logging. With this module removed in the new release, developers need to adopt an alternative logging method that continues to be reliable and compatible with Magento’s latest features.

How to Adapt: Switching to Zend_Log for Logging

    $writer = new \Laminas\Log\Writer\Stream(BP . '/var/log/custom.log');
    $logger = new \Laminas\Log\Logger();
    $logger->addWriter($writer);

So after 2.4.3+

With the removal of the Laminas-log module, Magento 2 now uses Zend_Log for logging, and here’s how to adjust your code:

  try {
        $writer = new \Zend_Log_Writer_Stream(BP . '/var/log/custom.log');
    } catch (\Zend_Log_Exception $e) {
        // throw exception
    }
    $logger = new \Zend_Log();
    $logger->addWriter($writer);
    $logger->info('Debuggging on!');

With the removal of the Laminas-log module in Magento 2.4.3, developers must update their logging strategies to use the Zend_Log component. This change brings a host of benefits, including improved performance, flexibility, and error handling.

By adopting the new logging method, Magento developers can continue debugging and monitoring their applications effectively without disruptions. It’s important to stay updated with these changes and always follow best practices to maintain a secure, efficient, and scalable Magento store.
