Creating event and observer for an action at backend of Magento 2

Question

How to create an custom event and observer for that event at backend in Magento2. For example I want to create an event that whenever an admin deletes a customer profile a separate log file is generated. Please help me with the detailed solution and the directory structure.

There is no option to delete the order in magento 2.....You can create event as order_cancel_after for cancel the order. — Ranganathan, Jul 13 '19 at 11:43

You can achieve this using plugin instead of events

Create di.xml in app/code/Vendor/Module/etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Customer\Model\ResourceModel\CustomerRepository">
        <plugin name="customer_delete_around" type="Vendor\Module\Plugin\aroundCustomerDelete" />
    </type>
</config>

And create a plugin with below code in Vendor\Module\Plugin\aroundCustomerDelete.php

<?php

namespace Vendor\Module\Plugin;

class aroundCustomerDelete
{
    public function aroundDeleteById(
        \Magento\Customer\Model\ResourceModel\CustomerRepository $subject,
        \Closure $proceed,
        $customerId
    ) {
        // This will proceed delete action
        $result = $proceed($customerId);

        $writer = new \Zend\Log\Writer\Stream(BP . '/var/log/test.log');
        $logger = new \Zend\Log\Logger();
        $logger->addWriter($writer);
        $logger->info('Your text message');

        return $result;
    }
}

Or you can create a custom log file using This link

Or use customer_delete_before this event to run your script in observer

I have already executed it using plugin I want to know if its possible using event and observer — Naiwrita09, Jul 13 '19 at 11:56
