授予 Database Insights 的精細存取權

精細存取控制提供額外的方法來控制對 Database Insights 的存取。此存取控制可以允許或拒絕存取 GetResourceMetrics、 DescribeDimensionKeys和 GetDimensionKeyDetails Database Insights 動作的個別維度。若要使用精細存取，請使用條件索引鍵在 IAM 政策中指定維度。存取的評估遵循 IAM 政策評估邏輯。如需詳細資訊，請參閱 IAM User Guide 中的 Policy evaluation logic。如果 IAM 政策陳述式未指定任何維度，則陳述式會控制對指定動作之所有維度的存取。如需可用維度的清單，請參閱 DimensionGroup。

若要了解您的憑證獲授權可存取的維度，請使用 ListAvailableResourceDimensions 中的 AuthorizedActions 參數並指定動作。AuthorizedActions 的允許值如下所示：

  • GetResourceMetrics

  • DescribeDimensionKeys

  • GetDimensionKeyDetails

例如，如果您將 GetResourceMetrics 指定為 AuthorizedActions 參數，則 ListAvailableResourceDimensions 會傳回 GetResourceMetrics 動作獲授權可存取的維度清單。如果您在 AuthorizedActions 參數中指定多個動作，則 ListAvailableResourceDimensions 會傳回這些動作獲授權可存取的維度交集。

範例

下列範例提供 GetResourceMetrics 和 DescribeDimensionKeys 動作指定維度的存取權。
