Cloud Monitor

Alert policies

Generating alert policies using templates

You can save alert rules for commonly used cloud product metrics to an alert template, and save collections of alert targets to an object group. When the resource types of an alert template and an object group overlap, Cloud Monitor will automatically generate the corresponding alert policies.

Background

Only when the resource types of an alert template and an object group overlap will Cloud Monitor automatically generate an alert policy.

Since alert templates and object groups are independent of each other, the impact of editing a configured alert template or object group on existing alert policies is shown in the following table.

Targets edited	Impact
Edit alert templates only.	The alert rules of generated alert policies will be synchronized with the updates.
Edit object groups only	The alert resources of generated alert policies will be synchronized with the updates.
Edit alert templates and object groups simultaneously	The alert rules and alert resources of generated alert policies will be synchronized with the updates.

When you delete a configured alert template or object group, the impact on already generated alert policies is shown in the following table.

Targets edited	Impact
Delete alert templates only	Generated alert policies will also be deleted.
Delete object groups only	The alert template needs to be unbound first. After unbinding, the generated alert policy will be deleted.
Delete alert templates and object groups simultaneously	Generated alert policies are deleted.

Prerequisites

Alert contacts and contact groups have been created. For details, see Creating contacts and contact groups.

Procedure

Step 1: Create an alert template

An alert template is a template that saves alert rules for various cloud product metrics, so that you can quickly create alert policies.

In the left navigation bar, click Alert Center > Alert Template.

Click Create alert template.

On the Create alert template page, complete the following configuration, then click Create.

Parameter	Descriptions	Sample value
Name	Specify a custom name for the alert template to identify the alert template. The name must be 1 to 128 characters in length. The name cannot start with a digit, a hyphen (-), or other special characters. The name can contain special characters.	Alerting templates
Description	Specify a custom description for the alert template.	test
Alert object	Configure the alert targets in the alert template. Resource type: From the drop-down menu, select the cloud product type to be monitored. Add dimension: Click Add dimension to specify the resource dimensions for the cloud product being monitored. Dimension: Specify the resource dimensions for the cloud product being monitored. Rule name: Specify a custom name for the alert rule. The name must be 1 to 64 characters in length. The name cannot start with a digit, a hyphen (-), or other special characters. The name can contain special characters. Metric type: Set the metric type for the alert. Available options include Single-metric or Multi-metric. Trigger condition: Set the metric, duration, statistical method, comparison operator, and threshold for the alert. If the monitored resource metric meets the trigger condition, the system will send an alert notification. If the Metric type parameter is set to Single metric, only one trigger condition can be set. If the Metric type parameter is set to Multiple metrics, one or more trigger conditions can be set. Duration: The duration can be set to 1 cycle, 3 cycles, 5 cycles, 10 cycles, 15 cycles, 30 cycles, 60 cycles, or 120 cycles. Comparison operator: The comparison operator can be set to >, >=, <, <=, !=, =, Compare to Last Period Increase, Compare to Last Period Decrease, Compare to Last Period Increase or Decrease, Compare to The Same Period of Yesterday Increase, Compare to The Same Period of Yesterday Decrease, Compare to The Same Period of Yesterday Increase or Decrease, Compare to The Same Period of Last Week Increase, Compare to The Same Period of Last Week Decrease, or Compare to The Same Period of Last Week Increase or Decrease. Alert level: indicates the severity level of the alert. Valid values: Critical, Warning, Notification. You can select different thresholds for different alert levels under the same condition.	-
Mute For	After an alert policy is triggered, if the monitored resource continues to trigger alerts, the system will periodically send alert notifications.	5 minutes
Notify mode	Rule: If any resource in an alert rule continuously exceeds the threshold during a notification cycle, only one alert will be sent within that cycle. Rule and resource: If different resources in the alert rule continuously exceed the alert threshold during the alert sending cycle, alert notifications will be sent for each resource. If metrics do not recover after the alert sending cycle, Cloud Monitor will send alert notifications again.	Rule
Alert recovery notification	An alert recovery notification is sent when the status of an alert policy returns to Normal. Cloud Monitor determines that an alert has been resolved.	Enable
NoData alert	If a resource reports no data for N consecutive periods, a NoData alert will be triggered.	Enable

tip

An alert template supports multiple cloud products and multiple dimensions.

Step 2: Create an object group

An object group is a collection of alert targets. It can contain instances of multiple products across multiple regions, and is applied to alert templates to define the scope of alert resources.

In the left navigation bar, click Object Group.

On the Object group list page, click Create object group.

On the Create object group page, finish configuration and then click Create.

Parameter	Descriptions	Sample value
Object group name	Object group name. The number of characters needs to be from 1 to 64. Only Chinese, English characters, and underscore _ are supported.	group_demo
resource type	Resource type: From the drop-down menu, select the cloud product type to be monitored. Selection method: Configure the resource selection method. Supports Manually select, Resource name, Project, and Label. Region: Select the region of the monitored resource. Select resource: From the list of available instances on the left, select the target instances and move them to the selected instances area on the right.	-

Step 3: Apply the alert template to the group

When the resource types of an alert template and an object group overlap, you can apply the template to the group. Cloud Monitor will then automatically generate the corresponding alert policies based on the intersecting resource types and dimensions.

warning

An Object group can only be bound to one alert template.

In the left navigation bar, click Alert center > Alert policy.

In the alert template list, find the target alert template and click Apply to Group in the Actions column on its right.

In the Apply alert template to object group pop-up window, click Add object group.

Expand the added object group, select the created object group and notification channel, then click Apply.

In the alert policy list, view the alert policy name.

When the resource types in an alert template and an object group overlap, Cloud Monitor automatically generates alert policies based on the common resource types and dimensions. The generated policies will be named in the format {Alert Rule Name}&{Object Group Name}, i.e., RuleForEcs&Group in this document.

tip

Alert policies generated from an alert template do not support editing or deletion. They only support enabling and disabling.
