Hello everyone, Today we will learn to create a custom log file programmatically and log data into the custom log file.<\/p>\n\n\n\n
First of all we need to create handlers and loggers for custom log file. For that, create a Logger.php class in Logger folder in your custom Module as shown below- <\/p>\n\n\n\n
<?php\nnamespace YourNamespace\\YourModule\\Logger;\n\nclass Logger extends \\Monolog\\Logger\n{\n}\n?><\/pre>\n\n\n\nAfter this, Create Handler class, in which we will define the custom Log file name as shown below-<\/p>\n\n\n\n
<?php\nnamespace YourNamespace\\YourModule\\Logger;\n\nuse Monolog\\Logger;\n\nclass Handler extends \\Magento\\Framework\\Logger\\Handler\\Base\n{\n protected $loggerType = Logger::INFO;\n\n protected $fileName = '\/var\/log\/customLog.log';\n}<\/pre>\n\n\n\nLast step is to define the monolog in di.xml in etc folder of your custom Module –<\/p>\n\n\n\n
<?xml version="1.0"?>\n<config xmlns:xsi="http:\/\/www.w3.org\/2001\/XMLSchema-instance" \n xsi:noNamespaceSchemaLocation="..\/..\/..\/..\/..\/lib\/internal\/Magento\/Framework\/ObjectManager\/etc\/config.xsd">\n <type name="YourNamespace\\YourModule\\Logger\\Handler">\n <arguments>\n <argument name="filesystem" xsi:type="object">Magento\\Framework\\Filesystem\\Driver\\File<\/argument>\n <\/arguments>\n <\/type>\n <type name="YourNamespace\\YourModule\\Logger\\Logger">\n <arguments>\n <argument name="name" xsi:type="string">myLoggerName<\/argument>\n <argument name="handlers" xsi:type="array">\n <item name="system" xsi:type="object">YourNamespace\\YourModule\\Logger\\Handler<\/item>\n <\/argument>\n <\/arguments>\n <\/type>\n<\/config><\/pre>\n\n\n\nThis is it, now just use the logger in your Magento 2 file, to print the logs in the custom created log file with the following code-<\/p>\n\n\n\n
<?php\nnamespace YourNamespace\\YourModule\\Model;\n\nclass TestModel\n{\n protected $_logger;\n\n public function __construct(\n \\YourNamespace\\YourModule\\Logger\\Logger $logger\n ) {\n $this->_logger = $logger;\n }\n\n public function testFunction()\n {\n $this->_logger->info('This is test Data to be print in customLog.log file');\n }\n}<\/pre>\n\n\n\nNow you can find the above printed data in var\/log\/customLog.log file. <\/p>\n\n\n\n
You can use this for logging any required data in your custom Module.<\/p>\n\n\n\n
This is all for now, I ll be back soon.<\/p>\n","protected":false},"excerpt":{"rendered":"
