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 prevent unwanted notifications.
You can customize the thresholds for the alert conditions, as well as update the policy to send notifications. For more information, see the Infrastructure alerts documentation.
To create new alert conditions based on Kubernetes metric data, see Manage alerts.
