Managed Service for Prometheus:Create and manage a notification policy

Create a notification policy

1. Log on to the Managed Service for Prometheus console. In the left-side navigation pane, choose Alert Management > Notification Policies.

2. In the upper-right corner of the Notification Policies page, click Create Notification Policy.

3. On the Create Notification Policy page, enter a notification policy name.

4. In the Matching Rule step, configure a matching rule for alert events.

   1. Select a data source.

      • If you specify a source of alert events, ARMS processes alert events of the specified data source and sends alert notifications based on the matching rule that you configured.

      • If you select No Preset Source, ARMS processes all alert events and sends alert notifications based on the matching rule that you configured.

   2. Specify one or more expressions. You can add custom tags or select existing tags.

      Existing tags include:

      • The fields that are included in an alert rule expression. For information about how to create a tag for an alert rule in Alibaba Cloud Managed Service for Prometheus, see Create an alert rule for a Prometheus instance.

      • The default tags that are provided by ARMS. The following table describes the default tags.

        Category	Tag	Description
        Common fields	alertname	The name of the alert.
        	clustername	The name of the Kubernetes cluster.
        	severity	The severity level of the alert. Valid values: P1 P2 P3 P4 Default
        	namespace	The name of the namespace. For more information, see Namespaces in Kubernetes documentation.
        	pod_name	The name of the Pod. For more information, see Pods in Kubernetes documentation.
        Preset system fields	_aliyun_arms_integration_name	The name of the integration that you specified as the data source. By default, ARMS returns the integration name ARMS-DEFAULT.
        	_aliyun_arms_involvedObject_id	The ID of the object that triggers the alert.
        	_aliyun_arms_involvedObject_name	The name of the object that triggers the alert.
        	_aliyun_arms_region_id	The region ID of ARMS.
        	_aliyun_arms_alert_rule_id	The ID of the alert rule.
        	_aliyun_arms_alert_type	The type of the alert rule. Valid values: 101: Prometheus alert 5: Application Monitoring alert 4: Browser Monitoring alert

      Note

      • If you want an alert to be triggered when multiple conditions are met at the same time, click + condition to add a matching condition in the same matching rule.

      • If you want an alert to be triggered when one condition is met, click + add rule to add a matching rule.

   3. Click Next.

5. In the Event Grouping step, select an option to specify whether to group alert events, and click Next.

   • If you specify that alert events are not grouped, all alert events are sent to the contacts in an alert notification.

   • If you specify that alert events are grouped, you must also specify a field. Alert events that have the same field value are grouped. Each group of alert events is sent to contacts in one alert notification.

6. In the Notification Objects step, configure the following parameters.

   1. Click + Add Notification Object to select contacts.

      Contact types:

      

      • Contact: When you select a contact, select a notification method, such as by phone call, text message, or email.

      • Contact group: When you select a contact group, select a notification method, such as by phone call, text message, or email.

      • Shift: When you select a shift, select a notification method, such as by phone call, text message, or email.

      • Instant messaging (IM) applications: You can send alert notifications to contacts from IM applications, including DingTalk, Lark, and WeCom.

      • Webhook: You can use a webhook to send alert notifications.

   2. Specify whether to send clearing notifications after an alert is cleared.

      If you choose to send clearing notifications after an alert is cleared, the status of an alert automatically changes to Resolved if all events related to the alert are handled. When an alert is cleared, the system sends clearing notifications to the contacts.

   3. Specify a notification template. For more information, see Configure a notification template and a webhook template.

   4. Specify the period of time during which alert notifications are sent.

   5. Optional:Select the ticket system to which alert notifications are sent. For more information, see Notification integrations.

   6. Click Next.

7. In the Policy to Repeat/Escalate/Clear Alerts step, specify whether to send repeat notifications, use an escalation policy, or manually clear alerts. Click Next.

   • If you do not use repeat notifications or an escalation policy, only one alert notification is sent before an alert is cleared.

   • If you want to send repeat notifications, configure an interval at which two alert notifications are sent. Alert notifications are continuously sent at the specified interval till an alert is cleared.

   • If you use an escalation policy, alert notifications are sent to other notification objects based on the escalation policy til an alert is cleared.

   • You can specify that alerts must be manually handled and cleared.

8. In the Action Integration step, specify whether to automatically implement action integrations.

   You can select action integrations that take effect when alerts are triggered and cleared.

9. Click Save.
