Try your stuff with below example:

public function coreBlockAbstractToHtmlBefore(Varien_Event_Observer $observer) {

 $block = $observer->getBlock();

if($block instanceof Mage_Page_Block_Html_Pager) {
        $collection = $block->getCollection();
        $pages = $block->getPages();
    }

}

Magento – Save admin name to order_status change using an Observer

EDIT:

You can also do the following, which I would recommend over the previous solution I posted. Mostly because it doesn't use setPost, which I would consider scary.

config.xml:

<adminhtml>
  <events>
    <sales_order_status_history_save_before>
      <observers>
        <module_status_history_save_before>
          <class>module/observer</class>
          <method>commentSaveBefore</method>
        </module_status_history_save_before>
      </observers>
    </sales_order_status_history_save_before>
  </events>
</adminhtml>

Observer.php:

public function commentSaveBefore($obs) {
    $event = $obs->getEvent();
    $status = $event->getDataObject();
    $status->setComment($status->getComment().$this->_getAppend());
}

protected function _getAppend()
{
    $admin = Mage::getSingleton('admin/session')->getUser();
    $username = $admin->getUsername();
    return " : " . $username;
}

This would accomplish the same thing, except you're intercepting the model before it gets saved, allowing you to alter the comment without having to use setPost().

Original Post: You could do the following:

config.xml:

<adminhtml>
    <events>
        <controller_action_predispatch_adminhtml_sales_order_addComment>
            <observers>
                <module_order_save_comment>
                    <class>module/observer</class>
                    <method>adminhtmlSavingOrderComment</method>
                </module_order_save_comment>
            </observers>
        </controller_action_predispatch_adminhtml_sales_order_addComment>
    </events>
</adminhtml>

Observer.php:

public function adminhtmlSavingOrderComment($obs) {
    $event = $obs->getEvent();
    $order = $event->getOrder();
    $data = Mage::app()->getRequest()->getPost('history');
    if ($data && isset($data['comment'])) {
        $data['comment'] .= $this->_getAppend();
        Mage::app()->getRequest()->setPost('history', $data);
    }
}

protected function _getAppend()
{
    $admin = Mage::getSingleton('admin/session')->getUser();
    $username = $admin->getUsername();
    return " : " . $username;
}

This should work for you.

Magento – How to get associated event name from observer

To get the name of the triggered event you can use the following code

class [Namespace]_[Module]_Model_Observer
{
   function myObserver(Varien_Event_Observer $observer)
   {
      $event = $observer->getEvent();
      var_dump($event->getName());
   }
}

to see what other data is in the Event object just call getData which will display all the stored data.

[...]
var_dump($event->getData());
[...]
