Finding the status of Magento cron jobs / tasks

Finding the status of Magento cron jobs / tasks

As covered in our last article, you should have a “cron job” (crontab) set up to run Magento’s cron.php file every so often (15 minutes or so is fine) via PHP directly on the server to take care of housekeeping tasks that keep Magento working well. Some other tasks, like updating tracking / inventory status, sending out newsletters, and other miscellaneous things also require that the crontab be properly set up, so if you haven’t taken care of that yet, please see the setup guide here, or contact support@nexcess.net and we can help you set it up.

Once your crontab is properly installed and configured, you might be curious as to what it’s actually doing behind the scenes, or you might want to verify that something did / did not happen, and when. Since Magento lacks this arguably critical information, we’ve whipped up a simple PHP script that can show you what’s scheduled, what’s running, and what already ran, along with all the other information hiding in the ‘cron_schedule’ table of your Magento database. Simply drop the script (linked to below) into your base HTML directory for Magento (usually this will be your “public_html” directory), change the file extension to “.php” instead of “.phps”, and load it up in your favorite browser.

You should see something like this:
Mage Cron

All of the fields should speak for themselves.

Copy and save the following PHP script.

<?php
 
// Parse magento's local.xml to get db info, if local.xml is found
 
if (file_exists('app/etc/local.xml')) {
 
$xml = simplexml_load_file('app/etc/local.xml');
 
$tblprefix = $xml->global->resources->db->table_prefix;
$dbhost = $xml->global->resources->default_setup->connection->host;
$dbuser = $xml->global->resources->default_setup->connection->username;
$dbpass = $xml->global->resources->default_setup->connection->password;
$dbname = $xml->global->resources->default_setup->connection->dbname;
 
}
 
else {
    exit('Failed to open app/etc/local.xml');
}
 
// DB Interaction
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to <a class="HelpLink" onclick="showHelpTip(event, hint_id_7); return false;" href="javascript:void(0)">mysql</a>');
mysql_select_db($dbname);
 
$result = mysql_query("SELECT * FROM " . $tblprefix . "cron_schedule") or die (mysql_error());
