Dummy module to show the behaviour of monitoring observable events using an observer. This observer simply logs pointless details from the request.
To install use the following composer command:
composer require yireo-training/magento2-example-observer:dev-master
Next enable the module:
bin/magento module:enable Yireo_ExampleObserver
bin/magento setup:upgrade
And flush the cache:
bin/magento cache:clean
After installing the module, every frontend action should be logged to var/log/system.log.
