Alerts are notifications of metric events triggered by anomalies, no data, or deviations from a static value.
Alert notifications are sent to recipients grouped according to distribution channels:
- Email – Recipients identified by an email address.
- Webhook – Recipients identified by a URL.
A Webhook is a simple event notification service via HTTP POST. When the alert is triggered, the service sends the alert payload to the specified URL.
- Slack – Recipients identified by WebHook URL created using Slack custom integration.
- Users – Recipients defined as users in host app.
Instances identify individual recipients within a notification channel.
