# Server (VPC) metrics

Available in VPC

This section provides information on the performance and operational metrics of the Server 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](/docs/en/management-cloudinsight) for information on how to use performance/operational metrics for monitoring.
