How to write your custom checks

Create a class which implements Chocofamily\PhalconHealthCheck\Services\Checks\ComponentCheckInterface and add it to healthcheck.php config file like

return [
    'componentChecks' => [
        'YOURCUSTOMCHECK' => YourCustomCheck::class
    ]
]

Responses

There is a configuration param which describes which response class to use to output the response. For example

• /health - Chocofamily\PhalconHealthCheck\Responses\ChocofamilyResponse::class output would look like this

{
    "data": {
        "DB": "OK",
        "CACHE": "OK",
        "SESSIONS": "CRITICAL",
        "STORAGE": "OK"
    }
}

Feel free to add your responses, if you want for example to output it in a view instead json.
