How to monitor swoole asynchronous task processing failure

Swoole When asynchronous task processing fails, the failure information can be captured by setting a listener. The specific steps are as follows: Create a failure callback function to handle failed task logic. Start the Swoole server. Handle failed task logic in the failure callback function, such as recording failure information, retrying the task, or notifying the user. Asynchronous task code should handle potential failure conditions and log or report any errors.

Swoole asynchronous task processing failure monitoring

In the Swoole framework, when asynchronous task processing fails, you can set a monitoring processor to capture and handle failure information. The following are the specific steps:

1. Create a failure callback function

<code class="php">use Swoole\Coroutine\Server;

// 创建 Server 对象
$server = new Server("0.0.0.0", 9501);

// 设置异步任务失败回调函数
$server->on('task_failed', function (Server $server, $task_id, $data) {
    // 处理失败任务逻辑
});</code>

2. Start the service

<code class="php">// 启动 Swoole 服务器
$server->start();</code>

3. Failed task processing logic

In the failure callback function, you can process the logic of the failed task as needed, for example:

• Record failure information:Write the failure information to the log or database for subsequent analysis of the problem.
• Retry the task: If the failure reason is not fatal, you can retry the task and give up after the number of retries reaches a certain threshold.
• Notify users: Notify relevant personnel of task failure via email or other means.

4. Asynchronous task code

Asynchronous task code should handle potential failure conditions and log or report any errors. For example:

<code class="php">// 处理异步任务的类
class MyTask
{
    public function run(Server $server, $task_id, $data)
    {
        try {
            // 执行任务逻辑
        } catch (Exception $e) {
            // 记录或报告错误信息
        }
    }
}</code>
