When an alert rule triggers a match in a notification policy, Application Real-Time Monitoring Service (ARMS) notifies the designated contacts by phone, text message, or email. Create and manage contacts to control who receives alert notifications and through which channels.
Supported notification channels
| Channel | Requirement |
|---|---|
| Phone call | Verified mobile number |
| Text message (SMS) | Verified mobile number |
| Email address | |
| DingTalk (mention in group) | User ID (optional) |
| Lark (mention in group) | User ID (required) |
| WeCom (mention in group) | User ID (required) |
DingTalk chatbots can no longer be configured as contacts. To create a DingTalk chatbot, go to the DingTalk/Lark/WeCom tab. For more information, see DingTalk chatbots. Existing DingTalk chatbots are not affected.

On the Contacts tab, click Create Contact.
In the Create Contact dialog box, configure the following parameters, and then click OK.
Parameter Description Name The name of the contact. Phone Number The mobile phone number of the contact. Alerts are sent by phone or text message. Only verified numbers are accepted.

Specify at least a mobile number or an email address. Each mobile number or email address can belong to only one contact.
Verify a mobile number
Verify a mobile number before it can receive alert notifications.
On the Contacts tab, locate the contacts whose mobile numbers need verification.
For a single contact, find the contact and click Not verified next to the number.

The system sends a verification text message to each selected contact.
Each contact opens the URL in the text message using a browser.
On the verification page, the contact confirms the number and clicks Verify.
