PHP enterprise-level application monitoring and log analysis

PHP Application Monitoring and Log Analysis: Application Performance Monitoring: Get detailed performance insights with New Relic APM tools. Use the XHPROF PHP extension to analyze function calls and identify bottlenecks. Logging: Use Monolog handles and loggers to log messages. Use ILogger to provide a standardized interface to different libraries. Practical case: Use New Relic APM and Monolog to monitor background tasks, report metrics and record progress.

PHP Enterprise Application Monitoring and Log Analysis

Introduction

In the enterprise In advanced applications, monitoring and log analysis are crucial to keeping the system running normally and detecting problems early. This article explores how to use PHP for comprehensive application monitoring and log analysis.

Application Performance Monitoring

• Using New Relic: New Relic is a popular Application Performance Monitoring (APM) tool that provides detailed code-level metrics and tracking information. It is easy to integrate into PHP applications and provides deep performance insights.

// 引入 New Relic PHP 代理
require 'newrelic.phar';
// 初始化 New Relic 代理
newrelic_start();

• Using XHPROF: XHPROF is a PHP extension that allows function calls to be profiled and profiled to identify performance bottlenecks.

// 安装 XHPROF PHP 扩展
pecl install xhprof
// 以启用 XHPROF 的方式运行脚本
php -d xhprof.enable_flag=1 script.php

Logging

• Using Monolog: Monolog is a powerful PHP logging library that provides a A consistent and configurable way to log messages.

// 创建一个 Monolog 句柄
$handler = new Monolog\Handler\StreamHandler('logs/application.log');
// 创建一个 Monolog 记录器
$logger = new Monolog\Logger('application');
// 为记录器添加句柄
$logger->pushHandler($handler);

// 日志一条信息
$logger->info('Application started');

• Using ILogger: ILogger is an extension to Monolog that provides an additional layer to the PHP-FIG canonical interface, allowing the use of different logging library implementations.

// 引用 ILogger 全局接口
use Psr\Log\LoggerInterface;

// 依赖注入一个 PSR-3 日志记录库
$logger = $container->get(LoggerInterface::class);

// 日志一条信息
$logger->info('Application started');

Practical case: Monitoring background tasks

Suppose we have a background task that performs a time-consuming task. To monitor this task, we can use New Relic to report metrics and Monolog to log its progress:

// 启动 New Relic APM 代理
newrelic_start();

// 引用 Monolog 记录器
use Monolog\Logger;

// 创建 Monolog 记录器
$logger = new Logger('background_task');

// 创建一个 New Relic 事务
$txn = newrelic_transaction_start('Background Task');

// 执行任务
$result = do_expensive_task();

// 标记 New Relic 事务结束
newrelic_transaction_end();

// 记录任务进度信息
$logger->info('Task completed with result: {result}', ['result' => $result]);

This results in a New Relic transaction that contains metrics about the task execution time and logged log messages. It will also create a log entry in the application log file recording the progress of the task.

Conclusion

By leveraging the powerful monitoring and logging libraries in PHP, comprehensive application monitoring and log analysis can be achieved. This is critical to keeping systems up and running, identifying performance bottlenecks and detecting problems early.
