Example of monitoring and alarm configuration in PHP Tencent Cloud Server API interface docking

PHP Monitoring and alarm configuration example in Tencent Cloud server API interface docking

Overview:
In the management and operation of cloud servers, the configuration of monitoring and alarm is important to ensure the stability and stability of the server. Security is paramount. Tencent Cloud provides a rich set of API interfaces to enable monitoring and alarm configuration of cloud servers. This article will use PHP code examples to introduce in detail how to configure monitoring and alarms on Tencent Cloud.

1. API preparation and calling
   First, we need to obtain Tencent Cloud’s API key information, including SecretId and SecretKey. In the code, we can configure the API's credential information in the following ways:

   $secretId = 'your_secret_id';
   $secretKey = 'your_secret_key';

   Next, we need to reference Tencent Cloud's SDK library file to call the corresponding API interface. Through the Composer tool, we can install dependent libraries:

   composer require qcloudapi/php-sdk

   Then, introduce the library file at the beginning of the code and instantiate the API interface:

   require_once 'vendor/autoload.php';
   use QcloudApiQcloudApi;

   Finally, we can pass parameters through the API interface And call the corresponding method to implement our operations:

   $config = [
    'SecretId' => $secretId,
    'SecretKey' => $secretKey,
    'RequestMethod' => 'POST',
    'DefaultRegion' => 'ap-guangzhou',
   ];
   $instance = QcloudApi::load(QcloudApi::MODULE_CVM, $config);

2. Monitoring configuration
   Tencent Cloud provides a rich set of monitoring indicators that can meet monitoring configurations for different needs. The following is a simple example that demonstrates how to configure CPU usage monitoring of a cloud server.

First, we need to set the monitoring period and frequency. In the code, we can configure it in the following way:

$monitorPeriod = 60; // 监控周期，单位秒，最大可设置为3600秒
$monitorFreq = 1; // 监控频率，单位秒，最小可设置为1秒，最大可设置为300秒

Then, we can add monitoring items through API calls:

$addMonitorParams = [
    'namespace' => 'QCE/CVM', // 命名空间，云服务器的监控项命名空间为QCE/CVM
    'dimensions.0.name' => 'unInstanceId', // 维度名称，指定云服务器实例
    'dimensions.0.value' => 'ins-xxxxx', // 维度值，指定云服务器实例的实例ID
    'period' => $monitorPeriod,
    'metricName' => 'CPUUsage', // 监控指标名称，指定要监控的指标为CPU使用率
    'unit' => 'Percentage', // 指标单位，CPU使用率的单位为百分比
];
$result = $instance->AddMonitor($addMonitorParams);

In the above code, we pass the corresponding parameters that is Monitoring items can be added. In this example, we will monitor the CPU usage of the server and configure the monitoring period, frequency, indicator unit and other parameters.

3. Alarm configuration
   After the monitoring items are configured, we also need to set up appropriate alarm rules so that we can receive timely notifications when an exception occurs on the server. The following is a simple example that demonstrates how to configure an alarm to be triggered when the cloud server CPU usage exceeds the threshold.

First, we need to set the threshold for the alert rule. In the code, we can configure it in the following way:

$thresholds = [
    [
        'ruleName' => 'CPUUsageAlarm', // 规则名称，自定义名称
        'period' => $monitorFreq * 3, // 统计周期，单位秒
        'comparisonOperator' => '>', // 比较运算符，大于
        'threshold' => 80, // 阈值，当CPU使用率大于80%时触发警报
        'times' => 3, // 连续达到阈值的次数
        'noticeWay' => ['sms', 'email'], // 通知方式，短信和邮件通知
    ],
];

Then, we can add the alert rule through the API call:

$addAlarmParams = [
    'namespace' => 'QCE/CVM',
    'name' => 'CPUUsageAlarmRule', // 警报规则名称，自定义名称
    'dimensions' => [
        [
            'name' => 'unInstanceId',
            'value' => 'ins-xxxxx',
        ],
    ],
    'thresholds' => $thresholds,
];
$result = $instance->AddAlarmPolicy($addAlarmParams);

In the above code, we pass the corresponding parameter i.e. Alert rules can be added. In this example, we set up a custom alert rule. When the server's CPU usage exceeds 80%, the alert is triggered when it reaches 3 times in a row, and notifications are sent via SMS and email.

Summary:
This article uses PHP code examples to introduce how to perform monitoring and alarm configuration in Tencent Cloud Server API interface docking. By configuring monitoring items and alarm rules, we can monitor the running status of the server in real time, handle abnormal situations in a timely manner, and ensure the stability and security of the server. At the same time, Tencent Cloud's API interface provides a wealth of parameters and methods to meet monitoring and alarm needs in different scenarios.
