Is it possible to profile Zend_Table queries? - zend-framework

Question

I'm looking for a way to profile queries which are performed internally by Zend_Table.
For example, after you finish Quickstart course, how to profile all the queries that are performed ?
I've tried to enable profiler from application.ini like this:
resources.db.profiler.class = "Zend_Db_Profiler_Firebug"
resources.db.profiler.enabled = true
And placed next rows in a Guestbook controller:
...
$db = Zend_Db_Table_Abstract::getDefaultAdapter();
$profiler = $db->getProfiler();
echo $profiler->getTotalElapsedSecs();
Which gives me 0
I've also tried to enable profiler in a Bootstrap file like this:
protected function _initProfiler() {
$this->bootstrap("db");
$profiler = new Zend_Db_Profiler_Firebug("All DB Queries");
$profiler->setEnabled(true);
Zend_Registry::get("db")->setProfiler($profiler);
}
Whick doesn't give me any result (I've installed and tested Firebug and FirePHP, using Zend_Log_Writer_Firebug())
I will appreciate any help. Thanks !

I've not tried the Firebug profiler. But I do use a html table to output profiler info at the bottom of each page that does a query.
enable profiler in application.ini
resources.db.params.profiler = true
render the profile results in the layout:
<?php
$this->addScriptPath(APPLICATION_PATH . '/views/scripts');
echo $this->render('profiler.phtml')
?>
profiler.phtml the view to render
<?php
// get the default db adapter
$adapter = Zend_Db_Table::getDefaultAdapter();
$profiler = $adapter->getProfiler();
if ($profiler->getEnabled() && $profiler->getTotalNumQueries() > 0) :
?>
<div style='text-align:center'>
<h2>Database Profiling Report</h2>
<p>Total queries executed: <?php echo $profiler->getTotalNumQueries() ?></p>
<p>Total elapsed time: <?php echo $profiler->getTotalElapsedSecs() ?></p>
</div>
<table class='spreadsheet' cellpadding='0' cellspacing='0' style='margin:10px auto'>
<thead>
<tr>
<th>#</th>
<th>Query</th>
<th>Time</th>
</tr>
</thead>
<tbody>
<?php foreach ($profiler->getQueryProfiles() as $queryNumber => $query) : ?>
<tr>
<td>(<?php echo $queryNumber + 1 ?>)</td>
<td><?php echo $query->getQuery(); ?></td>
<td><?php echo $query->getElapsedSecs(); ?></td>
</tr>
<?php endforeach ?>
</tbody>
</table>
<?php endif ?>
I don't imagine that using the firebug profiler is much more difficult.

The problem was in the parameters instantiation. When I've entered
resources.db.params.profiler.class = "Zend_Db_Profiler_Firebug"
resources.db.params.profiler.enabled = true
instead of previous configuration, everything went fine.
Note .params section of the parameter lines
