Alerting

Alert channels

Alert channels define where notifications are delivered when monitors, services, agents, or SLOs need attention.

Audience: Admins, on-call owners, SREs

Supported channels

  • Email: sends notifications to an email address.
  • Slack: sends alerts to a Slack Incoming Webhook URL.
  • Webhook: posts JSON payloads to a customer-owned endpoint.
  • SMS: sends text alerts to an E.164 phone number when the plan supports it.
  • WhatsApp: sends WhatsApp alerts to an E.164 phone number when configured and supported.

Setup guidance

  • Use labels that describe ownership, such as Platform on-call or Payments escalation.
  • Test every channel after creation so responders know delivery works before an incident.
  • For Slack, paste the hooks.slack.com Incoming Webhook URL, not the browser channel URL.
  • For SMS and WhatsApp, use E.164 format, for example +14155552671.

Governance

  • Creating, deleting, and testing alert channels requires owner or admin access.
  • Successful test sends are audit logged.
  • Delivery attempts are visible in alert delivery logs when incidents route through policies.
