Create an alert policy

Describes how to create an alert policy in the KSV web console.

This topic describes how to create an alert policy in the KubeSphere Virtualization (KSV) web console.

Prerequisites

The alerting feature is enabled. For information about how to enable alerting, see Enable and disable alerting.
The user that you use has been granted the permissions to manage alerts. Only user admin, project administrators, and operators can manage alerts. Project viewers can view only alerts in the projects to which they belong.

Procedure

Log in to the KSV web console.
In the top navigation bar, click O&M Tools to go to the management page of O&M tools.
In the left-side navigation pane, click Alerts.
On the Alert Policies tab, click Create in the upper-right corner.

In the dialog box that appears, configure basic information for the alert policy.

Parameter	Description
Name	The custom name of the alert policy. The name can contain only lowercase letters, digits, and hyphens (-), and must start and end with a lowercase letter or a digit. The name can contain up to 16 characters in length.
Alias	The alias of the alert policy. The alias can contain any characters and be up to 16 characters in length.
Duration (mins)	The duration of the alert. An alert is fired if the duration has been reached.
Severity	The severity of the alert. Valid values: Critical: an alert condition that requires immediate response. Major: an error without the need to take immediate action. Minor: a non-critical condition that has not caused a degradation in performance.
Description	The description of the alert policy. The description can be up to 128 characters in length. The character types are unlimited.
