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. ## Basic information The following is the basic information of the Cloud DB for PostgreSQL service for using performance/operational metrics. - Product name (`prodName`) - System/Cloud DB for PostgreSQL(VPC) - Product key (`cw_key`) - 680818728480411648 ## Performance/operation metrics The performance/operational metrics of the Cloud DB for PostgreSQL service are as follows. - Metric | Metric name | Data type | Unit | Metric type |
