I am learning observers and events, but following a simple event, i am unable to disect the problem, as to me it seems fine, and nothing in system.log as well. Following is my module etc/config.xml

<config>
        <events>
          <global>
            <customer_login>
                <observers>
                    <csv>
                        <type>model</type>
                        <class>csv/observer</class>
                        <method>logCSV</method>
                    </csv>
                </observers>
            </customer_login>
        </events>
 <global>
</config>

while my observer.php file is under Name_space/module_name/Model/Observer.php and has following code

class Training_Csv_Model_Observer{
    public function logCSV($observer){
    $customer = $observer->getCustomer();
    Mage::log($customer->getName()." has logged in", 
                null,
                "customer.log");
    
    }
}

I am unable to understand why this wouldn't work, as a simple Model would work, meaning my module is working and loading. My knowledge of PHP is limited and i want to know, why this won't work.
