Elasticsearch を使用して PHP アプリケーションのパフォーマンスを監視する方法

use ElasticsearchClientBuilder;

// 创建Elasticsearch客户端
$client = ClientBuilder::create()->build();

// 创建索引
$client->indices()->create([
    'index' => 'php_performance_monitoring',
]);

// 定义映射
$client->indices()->putMapping([
    'index' => 'php_performance_monitoring',
    'body' => [
        'properties' => [
            'timestamp' => ['type' => 'date'],
            'duration' => ['type' => 'float'],
            'endpoint' => ['type' => 'keyword'],
            'response_code' => ['type' => 'integer'],
        ],
    ],
]);

use MonologLogger;
use MonologHandlerElasticsearchHandler;

// 创建Monolog日志实例
$logger = new Logger('performance');

// 创建Elasticsearch处理程序
$handler = new ElasticsearchHandler($client, [
    'index' => 'php_performance_monitoring',
    'type' => 'log',
]);

// 添加处理程序到日志实例
$logger->pushHandler($handler);

// 记录性能监控数据
$logger->info('Performance monitoring', [
    'timestamp' => time(),
    'duration' => 0.753,
    'endpoint' => '/api/v1/users',
    'response_code' => 200,
]);

// 构建查询
$query = [
    'index' => 'php_performance_monitoring',
    'size' => 10,
    'body' => [
        'query' => [
            'match' => [
                'endpoint' => '/api/v1/users',
            ],
        ],
        'sort' => [
            'timestamp' => [
                'order' => 'desc',
            ],
        ],
    ],
];

// 执行查询
$response = $client->search($query);

// 处理查询结果
foreach ($response['hits']['hits'] as $hit) {
    $timestamp = $hit['_source']['timestamp'];
    $duration = $hit['_source']['duration'];
    $responseCode = $hit['_source']['response_code'];
    
    // 处理结果数据
    echo "Timestamp: " . date('Y-m-d H:i:s', $timestamp) . PHP_EOL;
    echo "Duration: " . $duration . "s" . PHP_EOL;
    echo "Response Code: " . $responseCode . PHP_EOL;
    echo PHP_EOL;
