Kubernetes integration: Predefined alert policy

When deploying the New Relic Kubernetes integration for the first time in an account, we deploy a default set of alert conditions to your account. The predefined alert policy, named Kubernetes default alert policy, doesn't have a notification channel by default to avoid unwanted notifications.

The alert conditions' thresholds can be customized to your environment and the alert policy updated to send notifications. For more information, see the Infrastructure alerts documentation.
