Note For more information about how to view the content of an event, see View system events.
   	SQL Filter	The SQL statements that you want to use for filtering. You can use the and and or operators. For example, if you set this parameter to Warn and i-hp368focau7dp0hw****, CloudMonitor sends alert notifications only when the event content contains the instance i-hp368focau7dp0hw**** and the alert level Warn.
   	Resource Range	The range of the resources to which the event-triggered alert rule is applied. Valid values: All Resources: The event-triggered alert rule is applied to all resources of the cloud service.

   Notification Method Note Select at least one alert notification method.	Alert Notification	CloudMonitor directly sends notifications of event-triggered alerts to the specified alert contact group. You must configure the following parameters: Alert Contact Group: The alert contact group to which the notifications of event-triggered alerts are sent. Notification Method: The severity level of event-triggered alerts and the corresponding notification methods. Valid values: Critical (Email + Webhook) Warning (Email + Webhook) Info (Email + Webhook)

   	Function Compute	The Function Compute function to which event-triggered alerts are delivered.
   	URL Callback	The callback URL that can be accessed over the Internet. CloudMonitor sends POST or GET requests to push alert notifications to the specified URL. You can enter only an HTTP URL. For more information about how to configure alert callbacks, see Configure callbacks for system event-triggered alerts (old). To test the connectivity of an alert callback URL, perform the following steps: Click Test next to the callback URL. In the Webhook Test panel, you can check and troubleshoot the connectivity of the alert callback URL based on the returned status code and test result details. Note To obtain the details of the test result, configure the Test Template Type and Language parameters and click Test. Click Close.
   	Simple Log Service	The Simple Log Service Logstore to which event-triggered alerts are delivered.
   	Mute For	The interval at which CloudMonitor resends alert notifications before an alert is cleared. Valid values: 5 Minutes, 15 Minutes, 30 Minutes, 60 Minutes, 3 Hours, 6 Hours, 12 Hours, and 24 Hours. If a metric value reaches the threshold, CloudMonitor sends an alert notification. If the metric value reaches the threshold again within the mute period, CloudMonitor does not resend an alert notification. If the alert is not cleared after the mute period ends, CloudMonitor resends an alert notification. For example, if the Mute For parameter is set to 12 Hours and the alert is not cleared, CloudMonitor resends an alert notification after 12 hours.
