Available in VPC

This section provides information on the performance and operational metrics of the Ncloud Kubernetes Service service. Performance/operational metrics can be managed in an integrated manner through NAVER Cloud Platform's Cloud Insight service and can be used for various monitoring purposes.

Note

See the Cloud Insight API Guide for information on how to use performance/operational metrics for monitoring.
