Contacts are the people who receive alert notifications from Managed Service for OpenTelemetry. When a notification policy rule triggers, the system sends alerts to the specified contacts by phone, text message, or email.
On the Contacts tab, you can:
Create and manage alert contacts
Verify mobile numbers for phone and text message notifications
Set a default fallback method when phone notifications fail
Edit or delete contacts individually or in bulk
