Overview

You can flexibly create alarm rules on the Cloud Eye console. You can create an alarm rule for a specific metric or event or use the alarm template to create alarm rules for multiple cloud service resources in batches.

Cloud Eye provides you with default alarm templates tailored to each service. In addition, you can also create custom alarm templates by modifying the default alarm template or by specifying every required field.

You can enable Alarm Notification when creating alarm rules. When a metric reaches the threshold specified in an alarm rule, Cloud Eye will notify you by email, HTTP or HTTPS message. You can track the service status and establish programs accordingly to handle the alarms.

**Table 1** Applicable scenarios
Alarm Type	Scenario
Metric	Cloud Eye can collect metric data of cloud services, such as CPU usage and memory usage. You can monitor metrics to track the status of cloud services. You can set alarm rules and notifications for core service metrics. When a metric triggers the preset threshold, Cloud Eye sends you a notification. This helps you identify and handle abnormal monitoring data in real time.
Event	Events are key operations or statuses of a cloud service, for example, restarting a VM. You can set event alarm rules for key business events or cloud resource operations. When a specified event occurs, Cloud Eye automatically sends an alarm notification. This helps you quickly identify and address issues.
