README

Add a simple status page to applications with custom checks.

The status page runs all registered checks and renders a page showing its results.

Installation

composer require bretrzaun/statuspage

Usage

$checker = new \BretRZaun\StatusPage\StatusChecker();
// add your checks here
$checker->addCheck(...);

// in different groups if you like
$group = new StatusCheckerGroup('Group 01');
$group->addCheck(...);
$group->addCheck(...);
$checker->addGroup($group);

// run the checks
$checker->check();

// use the built-in Twig template
$loader = new Twig_Loader_Filesystem('resources/views/');
$twig = new Twig_Environment($loader, ['autoescape' => false]);

$content = $twig->render(
    'status.twig',
        [
            'results' => $checker->getResults(),
            'title' => 'My status page'
        ]
    );
$code = $checker->hasErrors() ? 503 : 200;
// create a response with $content and $code

Out-of-the-box checks

• CallbackCheck: generic check using a PHP callback function
• DoctrineConnectionCheck: checks for a valid Doctrine DBAL connection
• ElasticsearchCheck: checks an Elasticsearch Client for successful pings
• LogFileContentCheck: check a (log) file for certain content
• MongoDbCheck: checks a MongoDB client
• PhpExtensionCheck: check a given PHP extension is loaded
• PhpIniCheck: check a value of php.ini
• PhpMemoryLimitCheck: check PHP memory limit
• PhpVersionCheck: check PHP version
• UrlCheck: checks a URL

Custom checks

Custom checks can be easily added by implementing BretRZaun\StatusPage\Check\CheckInterface or inheriting BretRZaun\StatusPage\Check\AbstractCheck.

Tests

To run the tests, just enter:

composer install
vendor/bin/phpunit
