     Multi-metric alert description	The multi-metric alert rule definition. Note Available only when Metric Type is Multiple Metrics and Standard Creation is selected.
     Relationship between metrics	How metrics are evaluated together. Valid values: Generate alerts if all metrics meet the conditions (&&) Generate alerts if any condition is met (||) Note Available only when Metric Type is Multiple Metrics and Standard Creation is selected.
     Multi-metric alert expression	The multi-metric alert expression. Configure expressions as described in Alert rule expressions. Note Available only when Metric Type is Multiple Metrics and Expression-based Creation is selected.
     Number of times the threshold must be reached before an alert is triggered	Consecutive periods a metric must meet the threshold to trigger an alert. Valid values: 1, 3, 5, 10, 15, 30, 60, 70, 90, 120, and 180.
     Method to handle alerts when no monitoring data is found	Action when monitoring data is unavailable. Valid values: Do not do anything Send alert notifications Mark as recovered

     Alert callback	A publicly accessible URL that receives alert notifications via HTTP POST requests. Use alert callbacks for threshold-based alerts. To test connectivity to the callback URL: Click Test, located directly to the right of the callback URL. In the WebHook Test panel, check the HTTP status code and test result details to verify connectivity. Note You can also set the Test Template Type: and Language:. Then click Test again to view updated test results. Click Close.

All Rules: Triggers when processes on an instance meet all rules. Any Rule: Triggers when processes on an instance meet any rule.
     Match expression	A dynamic rule for matching processes. Apply to all instances or only instances with a specific name pattern. Note Required only when Matching Rule is All Rules or Any Rule.
     Number of processes	The process count threshold.

   • Availability monitoring alert template

     Only ECS supports availability monitoring alerts. Parameters:

     Parameter	Description

     Detection address	The URL or IP address for the selected detection type.
     Request method	The HTTP probe method. Valid values: HEAD GET POST
     Match response content	Response content matching criteria. The probe reads the first 64 KB of the response body and matches against the specified content. Methods: Generate Alerts If Response Contains Generate Alerts If Response Does Not Contain Note Required only when Detection Type is HTTP(S).
     Status code	Triggers an alert when the probe status code matches the condition. An alert triggers if either Status Code or Response Time reaches its threshold, and is sent to the application group's contact group.
