I want to fire observer on customer login Page url(baseUrl."customer/account/login") magento 2.

I tried customer_login event but it's firing after customer login.

etc/events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">

 <event name="customer_login">
 <observer name="redirect_to_ccp_login" instance="VendorModuleObserverRedirectccpLogin" />
 </event>
</config>

VendorModuleObserverRedirectccpLogin.php

<?php 
namespace VendorModuleObserver;
use MagentoFrameworkControllerResultFactory;
class RedirectccpLogin implements MagentoFrameworkEventObserverInterface 

 protected $_logger;
 protected $resultFactory;
 protected $_responseFactory;

 public function __construct(
 MagentoFrameworkViewElementTemplateContext $context,
 PsrLogLoggerInterface $logger,
 MagentoFrameworkControllerResultFactory $resultFactory,
 MagentoFrameworkAppResponseFactory $responseFactory
 ) 
 $this->_logger = $logger;
 $this->resultFactory = $resultFactory;
 $this->_responseFactory = $responseFactory;
 

 public function execute(MagentoFrameworkEventObserver $observer) 
 $this->_logger->info("ccp customer login fire");

 

I overrided MagentoCustomerControllerAccountLogin Controller

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">

 <preference for="MagentoCustomerControllerAccountLogin" type="VendorModuleControllerCustomerLogin" />

</config>

VendorModuleControllerCustomerLogin.php

<?php

namespace VendorModuleControllerCustomer;
use MagentoFrameworkAppActionContext;
use MagentoFrameworkViewResultPageFactory;
use MagentoCustomerControllerAbstractAccount;
use MagentoCustomerModelSession;
use MagentoFrameworkControllerResultFactory;

class Login extends MagentoCustomerControllerAccountLogin
MagentoFrameworkViewResultPage
 */
 public function execute()
 

 $this->_logger->info("cpp customer login using controller.");

 

Above code worked for me

You can try using Plugin,

Create a di.xml file app/code/Vendor/Module/etc/di.xml file

<?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="MagentoCustomerControllerAccountLoginPost">
 <plugin name="customer_login_plugin" type="VendorModulePluginCustomerLoginPost" sortOrder="10" disabled="false"/>
 </type>
</config>

Create a Plugin file app/code/Vendor/Module/Plugin/Customer/LoginPost.php

<?php

namespace VendorModulePluginCustomer;

class LoginPost

 public function __construct(
 MagentoFrameworkAppActionContext $context
 ) 
 $this->_request = $context->getRequest();
 $this->_response = $context->getResponse();
 

 public function aroundExecute(MagentoCustomerControllerAccountLoginPost $subject, $proceed)
 
 $login = $this->_request->getPost('login'); 

 // before login check condition

 $returnValue = $proceed(); 

 // after login check condition

 return $returnValue;
 

Hope it helps.
