NDB can send alerts to which system?

NDB supports email-based alert notifications through a configured Simple Mail Transfer Protocol server. Administrators provide the SMTP server and sender information in NDB and then configure notification policies or recipient addresses for applicable alerts. This enables operational events, failures, and warning conditions to be delivered directly to administrators without requiring them to continuously monitor the NDB console. ServiceNow, Microsoft Teams, and PagerDuty are not identified as the native notification destination represented by this question. Such platforms may be connected indirectly through external automation, email ingestion, APIs, or webhook-based integrations, but those approaches are distinct from NDB’s built-in email notification capability. The official Nutanix documentation for configuring alert notifications specifically describes configuring an SMTP server so that NDB can send notifications by email.
