Log events into var/log/events.txt to debug and have more visibility on the observer events.
Install by composers or just download
composer require --dev alaa/magento2-events-logphp bin/magento alaa:events:log [area optional i.e global] - global
- frontend
- adminhtml
- webapi_rest
- webapi_soap
- graphql
Since some events are not actually used in the events.xml files, the events logged don't wholly include all events.
For example event customer_save_after is not used by Magento vanilla in any file, and so it is not logged when you run the command php bin/magento alaa:events:log.
