入参说明

查询云数据库（TDSQL-C MySQL）产品监控数据，入参取值如下：
&Namespace=QCE/CYNOSDB_MYSQL
&Instances.N.Dimensions.0.Name=InstanceId
&Instances.N.Dimensions.0.Value=CynosDB 数据库中具体实例的 ID
&Instances.N.Dimensions.1.Name=ProxyNodeId（即将下线，推荐使用 OssProxyNodeName）
&Instances.N.Dimensions.1.Value=CynosDB 数据库中代理节点的名称
&Instances.N.Dimensions.2.Name=OssProxyNodeName
&Instances.N.Dimensions.2.Value=CynosDB 数据库中代理节点的名称

重要说明

说明：
只读分析引擎的指标英文名（可以用于调用）需要在普通实例的指标英文名前加 Libra，例如：QPS 的指标英文名为 Qps，只读分析引擎对应为 LibraDBQps。
通过接口获取只读分析引擎的监控指标数据时，调用示例如下，当前支持的只读分析引擎监控指标请参见 监控告警。
