Managed Service for Prometheus sends alert notifications to contacts when a notification policy rule is triggered. Each contact defines one or more notification channels -- phone calls, text messages, or emails -- so the right people are reached through the right channels when alerts fire.
Supported notification channels
| Channel | Configuration |
|---|---|
| Phone call | Phone Number field |
| Text message (SMS) | Phone Number field |
| Email field | |
| DingTalk chatbot | DingTalk chatbot |
Specify at least one notification channel (phone number, email address, or DingTalk chatbot) for each contact. Each phone number or email address can belong to only one contact. Otherwise, alert notifications may not be processed by the relevant contact at the earliest opportunity.
Create a contact
Phone numbers must be verified before they can be referenced in a notification policy. If you add a phone number during contact creation, verify it immediately after (see Verify a phone number).
