Oh Dear module for Magento 2

This module adds Application health monitoring using Oh Dear to Magento 2. It allows you to easily write your own custom checks. Additionally, it ships with a number of checks out of the box.

Installation

composer require vendic/magento2-oh-dear-checks

Configuration

Some checks have an optional configuration. You can configure these checks in the env.php. Example:

    'ohdear' => [
        \Vendic\OhDear\Checks\CpuLoad::class => [
            'max_load_last_minute' => 10,
            'max_load_last_five_minutes' => 8,
            'max_load_last_fifteen_minutes' => 6
        ],
        \Vendic\OhDear\Checks\DatabaseConnectionCount::class => [
            'failed_treshold' => 100,
            'warning_treshold' => 80
        ],
        \Vendic\OhDear\Checks\PhpFpmCount::class => [
            'failed_treshold' => 100,
            'warning_treshold' => 80
        ],
    ]

Checks

TODO

Write your own checks

1. Create a new class that implements Vendic\OhDear\Interfaces\CheckInterface, place it in 'Checks'. This class will contain the main logic of your check.
2. Add your new class to the 'checks' argument of Vendic\OhDear\Api\CheckListInterface

    <type name="Vendic\OhDear\Api\CheckListInterface">
        <arguments>
            <argument name="checks" xsi:type="array">
                ...
                <item name="your_new_check" xsi:type="object">Vendic\OhDear\Checks\YourNewCheck</item>
                ...
            </argument>
        </arguments>
    </type>

3. Preferabbly add a test for your check. See Vendic\OhDear\Test\Integration\Checks\ for examples.
4. Test your output on: https://magento2.test/oh-dear-health-application-check-results. Your GET request should include the header oh-dear-health-check-secret. The header value should match the Magento config value of ohdear/health_check/secret. If you don't have this header, you will get a 'No health secret provided' response.
5. Open a PR with your new check!
