A framework for the implementation of proactive Magento health checks

Proactive Magento Health Checks

There are often metrics in a project that dictate the health of an online store, some examples:

• Has there been an order placed in the last hour?
• Are there any orphaned Sage Pay transactions?
• Is the reindexing process stuck?

This extension provides a framework for the implementation of proactive Magento 'health checks', run every five minutes, with email notifications to designated contacts if a problem occurs.

Installation

modman clone [email protected]:meanbee/meanbee-magento-healthcheck.git
modman deploy meanbee-magento-healthcheck

Architecture

• A check is an implementation of Meanbee_Healthcheck_Model_CheckInterface
• Checks are registered with healthcheck through XML configuration
• Checks are executed every five minutes through a centralised healthcheck cron
• Checks are responsibile for building an alert (Meanbee_Healthcheck_Model_Alert) and passing it through to the notify method (Meanbee_Healthcheck_Helper_Alert::notify)

Usage

Documentation below describes how a developer might go about implementing a check and plugging it into healthcheck.

Implementing a check

A check is a model that implements an interface: Meanbee_Healthcheck_Model_CheckInterface. An abstract check class is provided with useful utility methods in Meanbee_Healthcheck_Model_Check_Abstract.

A check must implement a check method. Inside of the check method the developer must implement their test logic and notify with an alert if appropriate.

The following example creates an alert and notifies the administrators about the alert.

    class Meanbee_HealthcheckExample_Model_Check_Test extends Meanbee_Healthcheck_Model_Check_Abstract
    {
        public function check()
        {
            $this->log("Starting check..");

            /** @var Meanbee_Healthcheck_Model_Alert $alert */
            $alert = Mage::getModel('meanbee_healthcheck/alert');
            $alert
                ->setName(__CLASS__)
                ->setSeverity(Zend_Log::DEBUG)
                ->setMessage("This is a test check")
                ->setStackTrace(debug_backtrace());

            Mage::helper('meanbee_healthcheck/alert')->notify($alert);

            $this->log("Check complete.");
        }
    }

Registering the check

Next we need to register the check with healthcheck. This is done through configuration XML.

    <config>
        ...
        <meanbee_healthcheck>
            <checks>
                ...
                <my_example_test>
                    <class>Meanbee_HealthcheckExample_Model_Check_Test</class>
                </my_example_test>
                ...
            </checks>
        </meanbee_healthcheck>
        ...
    </config>

By registering of the checks through XML, the healthcheck extension can pick up any checks in third party extensions.

Configuration

There are configuration options in Advanced > Meanbee Healthcheck to set email addresses for notifications.

Roadmap

• Allow schedules to specified by individual checks
• Store alerts in a database table for providing an administration dashboard
