ThinkPHP6 application monitoring and alarm: real-time monitoring of application status

In modern Internet application development, the stability and reliability of applications have received more and more attention. Application monitoring and alarming are one of the important means to ensure the normal operation of applications. This article will introduce how to use the application monitoring and alarm functions of ThinkPHP6 to monitor application status in real time and discover and solve potential problems in a timely manner.

1. Preparation

1. Installation dependencies

ThinkPHP6’s application monitoring and alarm functions rely on third-party componentsswooletw/monitor and swooletw/alerter. First, you need to execute the following command in the project root directory to install these two dependencies:

composer require swooletw/monitor swooletw/alerter

2. Configuring the swoole coroutine environment

ThinkPHP6’s application monitoring and alarm functions are based on swoole asynchronous When developing coroutines, you need to ensure that the swoole extension has been installed in the environment and the swoole coroutine environment has been configured.

3. Modify the configuration file

Open the config/monitor.php file in the project root directory and configure the monitoring parameters. Here you can configure the monitored application name, refresh frequency, monitoring indicators, alarm rules, etc.

2. Real-time monitoring of application status

1. Create a monitoring manager

First, we need to create a monitoring manager to handle the collection and collection of monitoring data storage. Create the app/monitor directory in the project root directory, and create the Manager.php file in this directory. The file content is as follows:

<?php

namespace appmonitor;

use SwooleCoroutine;

class Manager
{
    protected $data = [];

    public function save($info)
    {
        $this->data[Coroutine::getCid()] = $info;
    }
}

The monitoring manager uses the protocol The process context stores monitoring data, and each coroutine will have its own monitoring data.

2. Register monitoring middleware

Open the middleware.php file in the project root directory and add the following code at the end of the file:

<?php

// 注冊監(jiān)控中間件
$app->middleware(ppmiddlewareMonitor::class);

3. Create monitoring middleware

Create the app/middleware directory in the project root directory, and create Monitor.php in this directory file, the content of the file is as follows:

<?php

namespace appmiddleware;

use appmonitorManager;
use thinkacadeRequest;

class Monitor
{
    public function handle($request, Closure $next, $config)
    {
        // 獲取當(dāng)前請求信息
        $info = [
            'request_uri' => Request::url(),
            'request_method' => Request::method(),
            //... 其他監(jiān)控信息
        ];

        // 通過Manager保存監(jiān)控?cái)?shù)據(jù)
        $manager = new Manager();
        $manager->save($info);

        // 繼續(xù)執(zhí)行后續(xù)中間件和控制器
        return $next($request);
    }
}

This middleware will save the request-related information to the monitoring manager every time a request enters the application.

3. Alarm function

1. Create alarm manager

Create the app/monitor directory in the project root directory, in Create the Alerter.php file in this directory. The file content is as follows:

<?php

namespace appmonitor;

use SwooleCoroutine;

class Alerter
{
    public function alert()
    {
        // 獲取監(jiān)控?cái)?shù)據(jù)
        $manager = new Manager();
        $data = $manager->data;

        // 檢查監(jiān)控?cái)?shù)據(jù)，觸發(fā)報(bào)警邏輯
        foreach ($data as $cid => $info) {
            // ... 檢查監(jiān)控?cái)?shù)據(jù)并觸發(fā)報(bào)警邏輯
        }
    }
}

The alarm manager will periodically check the monitoring data and trigger the alarm logic.

2. Register alarm task

Open the appConsolecommand.php file in the project root directory, and add the following code at the end of the file:

<?php

// 注冊報(bào)警任務(wù)
$app->command('monitor:alert', ppmonitorAlertCommand::class);

3. Create Alert Command

Create the app/monitor directory in the project root directory, and create the AlertCommand.php file in this directory, The content of the file is as follows:

<?php

namespace appmonitor;

use thinkconsoleCommand;
use thinkconsoleInput;
use thinkconsoleOutput;

class AlertCommand extends Command
{
    protected function configure()
    {
        $this->setName('monitor:alert')
            ->setDescription('Alert when monitor data exceeds thresholds');
    }

    protected function execute(Input $input, Output $output)
    {
        $alerter = new Alerter();
        $alerter->alert();

        $output->writeln('Alerting task has been executed');
    }
}

This alarm command will periodically call the alert() method of the alarm manager to perform alarm checking.

4. Run application monitoring and alarming

Run the following command in the command line to start the application monitoring and alarming function:

php think monitor:alert

You can customize monitoring indicators and alarms as needed rules to further improve application monitoring and alarm functions. When the monitoring data exceeds the set threshold, the alarm logic will be triggered to handle and solve potential problems in a timely manner, improving the stability and reliability of the application.

Summary

Application monitoring and alarming are one of the important means to ensure application stability and reliability. This article introduces how to use application monitoring and alarm functions in ThinkPHP6 applications, and gives corresponding code examples. By monitoring application status in real time, we can quickly discover and solve potential problems and improve application stability and reliability.
