Alerting silence policy

Creating an alerting silence policy

The alert silence policy is used to silence specified alerts. When some alerts cannot be resolved, you can configure an alert silence policy to silence the notifications of the corresponding alerts. This topic describes how to configure an alert silence policy.

tip

The new Alert Center is available. It provides comprehensive upgrades and optimizations for features such as notification policies, notification templates, aggregation policies, and suppression policies. We recommend configuring suppression policies in the new Alert Center.

Prerequisites

VMP has been activated.

Limits

Up to 1,000 alert silence rules can be created within a root user and its Identity and Access Management (IAM) users.

Procedure

Manual configuration

In the top navigation bar, select the target region.

On the left navigation bar, click Alert center > Alerting silence policy. On the page that appears, click Create silence policy and configure the policy.

Parameter	Descriptions
Policy Name	Specify the name of the alert silence policy. It is a string and can contain Chinese characters, uppercase and lowercase letters, digits, underscores (_), and hyphens (-). It cannot start with a digit, underscore (_), hyphen (-), or any other special character. It must be 1 to 128 characters in length.
Description	Specify the description of the alert silence policy. The description must be 1 to 128 characters in length.
Silence machers	Use the labels included in the alerts to match the alerts that you want to silence. Example: job:kubernetes-etcd. You can configure multiple label groups. Each label group can contain multiple labels. tip The logical OR relationship applies between label groups. The logical AND relationship applies between labels within a label group. In addition to the labels in alert events, the __alerting_rule_id label (alert rule ID) is also supported. You can use this label to search for the target alert rule.
Silence time	Configure the effective time period of the alert silence policy. Valid values: Always: The alert silence policy always takes effect. Periodic: The alert silence policy only takes effect within a specified time period on each day. Click Start time and End time to specify the effective time periods of the alert silence policy on each day. You can specify up to 3 time periods. Custom: The alert silence policy takes effect during the specified time periods on specified dates. Click Start date and End date to specify the effective time periods of the alert silence policy. You can configure up to 3 time periods.

Click Create to complete the configuration.

Configuration through alert notification

When you receive alert notifications in Feishu, you can create an alert silence rule by using the notifications.

When you receive a Feishu alert notification, click the silence button at the bottom of the notification.

Then, you are redirected to the VMP console. The system automatically creates a silence policy and fills in the parameters.

You need to modify the Silence matchers and Silence time parameters based on your business requirements. Then, click OK to complete the configuration.
