#Management of Notification

#Feature Overview

With notifications, you can integrate the platform's monitoring and alerting features to promptly send pre-warning information to notification recipients, reminding relevant personnel to take necessary measures to resolve issues or avoid failures.

#Key Features

• Notification Server: The notification server provides services for sending notification messages to notification contact groups on the platform, such as an email server.
• Notification Contact Group: A notification contact group is a set of notification recipients with similar logical characteristics, which can reduce your maintenance burden by allowing a categorization of entities that receive notification messages.
• Notification Template: A notification template is a standardized structure composed of custom content, content variables, and content format parameters. It is used to standardize the content and format of alert notification messages for notification strategies. For example, customizing the subject and content of email notifications.
• Notification rule: A notification rule is a collection of rules defining how to send notification messages to specific contacts. It is essential to use a notification rule for scenarios such as alerts, inspections, and login authentication that require notifying external services.

#Notification Server

The notification server provides services for sending notification messages to recipients on the platform. The platform currently supports the following notification servers:

• Corporate Communication Tool Server: Supports integration with WeChat Work, DingTalk, and Feishu built-in applications for sending notifications to individuals.
• Email Server: Sends notifications via email using an email server.
• Webhook Type Server: Supports integration with corporate WeChat group bots, DingTalk group bots, Feishu group bots, or sending WebHooks to your designated server.

#Notification Template

A notification template is a standardized structure composed of custom content, content variables, and content format parameters. It is used to standardize the content and format of alert notification messages for notification strategies.

Platform administrators or operations personnel can set notification templates to customize the content and format of notification messages based on different alert notification methods, helping users quickly get critical alert information and improve operational efficiency.

#Create Notification Template

1. In the left navigation bar, click Operations Center > Notifications.

2. Switch to the Notification Template tab.

3. Click Create Notification Template.

4. In the Basic Information section, configure the following parameters.

   Parameter	Description
   Message Type	Select the type of message according to the purpose of the notification. Alert Message: Sends alert messages triggered by alert rules, in conjunction with the platform's alerting functionality; Component Exception Message: Sends notification information triggered by exceptions in certain components.

5. In the Template Configuration section, reference different template types to configure variables and content formatting parameters.

6. Click Create.

#Reference Variables

Variables are the keys of labels or annotations in notification messages (NotificationMessage), formatted as {{.labelKey}}. To facilitate users in quickly obtaining key information, custom display names can be assigned to variables; for example: Alert Level: {{ .externalLabels.severity }}.

When a notification rule sends notification messages to users based on a notification template, the variables in the template will reference the corresponding label values in the notification message (actual monitoring data). Ultimately, monitoring data will be sent to users in a standardized content format.

The platform provides the following basic variables by default:

Display Name	Variable	Description
Alert Status	{{ .externalLabels.status }}	For example: Alerting.
Alert Level	{{ .externalLabels.severity }}	For example: Critical.
Alert Cluster	{{ .labels.alert_cluster }}	For example: Cluster 1 where the alert occurred.
Alert Object	{{ .externalLabels.object }}	The type and name of the resource where the alert occurred, e.g., node 192.168.16.53.
rule Name	{{ .labels.alert_resource }}	The name of the alert rule, e.g., cpaas-node-rules.
Alert Description	{{ .externalLabels.summary }}	Description of the alert rule.
Trigger Value	{{ .externalLabels.currentValue }}	The monitored value that triggered the alert.
Alert Time	{{ dateFormatWithZone .startsAt "2006-01-02 15:04:05" "Asia/Chongqing" }}	The start time of the alert.
Recovery Time	{{ dateFormatWithZone .endsAt "2006-01-02 15:04:05" "Asia/Chongqing" }}	The end time of the alert.
Metric Name	{{ .labels.alert_indicator }}	Name of the monitoring metric.
