How to use the Hyperf framework for log analysis

Introduction:
Log analysis is a very important task when developing and maintaining a Web application. By analyzing system logs, we can obtain key information about system performance, errors, and user behavior, which can help us optimize and improve our applications. In this article, we will introduce how to use the Hyperf framework for log analysis and provide specific code examples.

1. Overview of the log module of the Hyperf framework
The Hyperf framework is an extensible lightweight framework developed based on the PHP language. It is high-performance and flexible, and is suitable for building various types of web applications. In the Hyperf framework, the logging module is an important component. It provides rich functions and interfaces to facilitate the collection, storage and analysis of system logs.

2. Configure the log component of the Hyperf framework
Before using the Hyperf framework for log analysis, we first need to configure the log component. In the Hyperf framework, the configuration information of the log component is stored in the config/autoload/logger.php file. The following is a simple configuration example:

<?php
return [
    'default' => [
        'handler' => [
            'class' => MonologHandlerStreamHandler::class,
            'constructor' => [
                'stream' => BASE_PATH . '/runtime/logs/hyperf.log',
                'level' => MonologLogger::DEBUG,
            ],
        ],
        'formatter' => [
            'class' => HyperfLogFormatterFormatterFactory::class,
            'constructor' => [
                'format' => null,
                'output' => "[%datetime%] %channel%.%level_name%: %message% %context% %extra%
",
                'formatter' => MonologFormatterLineFormatter::class,
                'formatterConstructor' => [
                    'format' => null,
                    'dateFormat' => 'Y-m-d H:i:s',
                    'allowInlineLineBreaks' => true,
                ],
            ],
        ],
    ],
];

In the above configuration, we specify the default log handler as StreamHandler, and save the log output in runtime/ logs/hyperf.log file. In addition, we also define the log formatting method, including date format, log level, etc.

After configuring the log component, we can use the logging function in other components of the Hyperf framework.

3. Using the log component of the Hyperf framework
The log component of the Hyperf framework provides a wealth of interfaces and methods to facilitate us to record and analyze system logs. The following are some commonly used examples:

1. Record a common log message:

<?php
use HyperfUtilsApplicationContext;
use PsrLogLoggerInterface;

$container = ApplicationContext::getContainer();
$log = $container->get(LoggerInterface::class);

$log->info('This is a log message');

In the above example, we first obtain from the Hyperf container An instance of the LoggerInterface interface, and then calls the info() method to record a common log information.

2. Record logs with contextual information:

<?php
use HyperfUtilsApplicationContext;
use PsrLogLoggerInterface;

$container = ApplicationContext::getContainer();
$log = $container->get(LoggerInterface::class);

$log->warning('This is a warning message', ['user_id' => 123456]);

In the above example, we used the warning() method to record a strip Logs with contextual information. This context information can be any key-value pair, used to provide more context about the log information.

3. Filter log information based on log level:

<?php
use HyperfUtilsApplicationContext;
use PsrLogLoggerInterface;
use MonologLogger;

$container = ApplicationContext::getContainer();
$log = $container->get(LoggerInterface::class);

$log->pushProcessor(function ($record) {
    if ($record['level'] >= Logger::WARNING) {
        return $record;
    }
});

$log->warning('This is a warning message');
$log->debug('This is a debug message');

In the above example, we used the pushProcessor() method to filter log information. In this example, we only print information with a log level greater than or equal to WARNING, so only warning information will be output.

4. Conclusion
In this article, we introduced how to use the Hyperf framework for log analysis. By configuring and using the log component of the Hyperf framework, we can easily record and analyze system log information. I hope this article can help you better understand and apply the logging function of the Hyperf framework.

The above is an introduction and sample code about Hyperf framework log analysis, which will help you better utilize the Hyperf framework for log analysis in actual development. Good luck with your project!
