magento2 zend log

The Zend\Log component in Magento 2 is used for logging purposes. It provides a flexible and extensible logging framework that allows developers to log messages to various output channels, such as files, databases, or custom log writers.

To use the Zend\Log component in Magento 2, you need to follow these steps:

  1. Create a logger instance: ```php use Zend\Log\Logger; use Zend\Log\Writer\Stream;

$logger = new Logger(); $writer = new Stream('path/to/log/file.log'); $logger->addWriter($writer); ```

  1. Log messages: php $logger->info('This is an informational message'); $logger->error('This is an error message'); $logger->debug('This is a debug message');

  2. Customize log formatting and filtering (optional): ```php use Zend\Log\Formatter\Simple; use Zend\Log\Filter\Priority;

$formatter = new Simple('[%timestamp%] %priorityName%: %message%'); $writer->setFormatter($formatter);

$filter = new Priority(Logger::INFO); $writer->addFilter($filter); ```

Please note that the above code is just an example and you may need to adjust it based on your specific requirements.
