PHP Performance monitoring and tuning skills in Huawei Cloud API interface docking

With the development of cloud computing, more and more enterprises are beginning to choose to deploy their services on cloud platforms. As a leading cloud computing service provider in China, Huawei Cloud provides a rich set of API interfaces to facilitate developers to develop customized applications. However, in large-scale API interface docking, performance monitoring and tuning are a key part, which can help us better improve the performance and stability of the system. This article will introduce performance monitoring and tuning techniques in PHP Huawei Cloud API interface docking, and illustrate it through code examples.

1. Performance Monitoring

Performance monitoring refers to the real-time monitoring of all aspects of the system in order to promptly discover system bottlenecks and performance problems. In PHP Huawei Cloud API interface docking, we can monitor performance in the following ways:

1. Logging

In PHP development, we usually use logs Records to help us locate the problem. During the API interface docking process, we can use logging to record request and response times, as well as other key information. Here is a simple example:

$logTime = date("Y-m-d H:i:s");
$requestUrl = 'https://api.huaweicloud.com/v1/xx/xx';
$requestData = [
    'key1' => 'value1',
    'key2' => 'value2',
    // ...
];

$startTime = microtime(true);
$response = $client->post($requestUrl, ['json' => $requestData]);
$endTime = microtime(true);

$log = sprintf("[%s] 请求：%s 结果：%s 耗时：%.2f秒", $logTime, $requestUrl, $response->getBody(), $endTime - $startTime);
file_put_contents('api.log', $log . PHP_EOL, FILE_APPEND);

In the above code, we calculate the request and response by using the microtime(true) function to get the microsecond part of the current timestamp. It takes time and writes the log to the api.log file.

2. Performance Statistics

In addition to basic logging, we can also use some performance statistics tools to help us better understand the performance of the system. For example, you can use swoole's performance monitoring function to perform performance statistics. The following is a simple example:

$swooleHttpServer = new SwooleHttpServer('127.0.0.1', 9501);

$swooleHttpServer->on('Request', function (SwooleHttpRequest $request, SwooleHttpResponse $response) {
    // 处理请求...
});

$swooleHttpServer->on('WorkerStart', function (SwooleHttpServer $server, int $workerId) {
    // 启动性能统计
    SwooleRuntime::enableCoroutine(SWOOLE_HOOK_TCP | SWOOLE_HOOK_HTTP2 | SWOOLE_HOOK_FAST_CGI);
    SwooleCoroutine::create(function () {
        while (true) {
            $stats = SwooleCoroutine::stats();
            file_put_contents('swoole.stats.log', json_encode($stats) . PHP_EOL, FILE_APPEND);
            
            $memoryUsage = memory_get_usage(true);
            file_put_contents('swoole.memory.log', $memoryUsage . PHP_EOL, FILE_APPEND);
            
            sleep(1);
        }
    });
});

$swooleHttpServer->start();

In the above code, we recorded the statistical information of the Swoole client through swoole.stats.log, including the number of connections, the number of coroutines, and the scheduler Status, etc.; the memory usage is recorded through swoole.memory.log. By constantly counting these data, we can make corresponding optimizations and adjustments as needed.

2. Performance Tuning

Once performance problems are discovered, we need to optimize and adjust accordingly. In the PHP Huawei Cloud API interface docking, performance tuning mainly focuses on the following aspects:

1. Optimizing network communication

Network communication is inevitable in API interface docking We can optimize network communication performance through the following points:

• Use HTTP/2 protocol: Compared with HTTP/1.1 protocol, HTTP/2 protocol has higher performance and lower cost delay, which can significantly improve the efficiency of network communication.
• Enable connection pool: Using connection pool can avoid frequently establishing and closing connections and reduce network communication overhead.
• Enable compression: Enabling compression can reduce the amount of data in requests and responses, and improve the efficiency of network communication to a certain extent.

2. Optimize database access

In API interface docking, database access is a common performance bottleneck. We can optimize database access performance through the following points:

• Reduce the number of database accesses: Try to reduce the number of database accesses through batch operations, transactions, etc., thereby improving performance.
• Introduce caching: For frequently accessed data, a caching mechanism can be introduced to reduce database access and improve performance.
• Use indexes: Proper use of indexes can improve the query performance of the database.

3. Optimize code logic

Code logic is another important factor that affects system performance. We can optimize code logic through the following points:

• Use loops and recursion with caution: Loops and recursive operations can easily cause performance problems when processing large-scale data, and should be avoided or optimized. .
• Avoid repeated calculations: For some operations whose calculation results remain unchanged, you can avoid repeated calculations and improve performance by caching the results.
• Reasonable use of cache: For some time-consuming operations, such as reading files, accessing databases, etc., you can use cache to improve performance when necessary.

In summary, performance monitoring and tuning are very important in PHP Huawei Cloud API interface docking. Through reasonable performance monitoring and tuning, we can optimize system performance and stability and improve user experience. In actual development, we need to choose appropriate performance monitoring and tuning methods based on specific business scenarios and needs, and make corresponding optimizations and adjustments based on actual conditions. We believe that through continuous optimization and tuning, we can better leverage the performance and benefits of the PHP Huawei Cloud API interface.
