十六、各维度对应参数总览

参数名称 维度名称 维度解释 格式
Instances.N.Dimensions.0.Name target target 维度名称 输入 String 类型维度名称:target
Instances.N.Dimensions.0.Value target 视查询维度而定 请参见 取值参照表 取值

注意:云数据库 Instances.N.Dimensions.0.Value 的取值:
腾讯云提供的 MongoDB 为集群服务,可以查询“整个集群”、“某个副本集”、“某个节点”三个维度的监控数据:

十七、dimensions.0.value 取值参照表

取值类型 取值示例 描述
实例 ID cmgo-6ielucen 实例 ID,一个 MongoDB 实例的唯一标识:可以在 MongoDB 控制台 获取或者调用 MongoDB 的 API 获取
副本集 ID cmgo-6ielucen_0cmgo-6ielucen_2 在实例 ID 后面拼接 “_索引号”可以得到副本集 ID。“索引号”从0开始,最大值为副本集个数-1;副本集实例只有一个副本集,所以固定拼接“_0”即可;分片实例有多个片,每一片都是副本集,例如:第3个片的副本集 ID 就是拼接“_2”
Mongod 节点 ID cmgo-6ielucen_0-node-primarycmgo-6ielucen_1-node-slave0cmgo-6ielucen_3-node-slave2 在副本集 ID 后面拼接“-node-primary”得到该副本集的主节点 ID在副本集 ID 后面拼接“-node-slave 从节点索引号”可得到对应的从节点的 ID,“从节点索引号”从0开始,最大值为从节点个数-1
Mongos 节点 ID cmgo-6ielucen-node-mongos0 在实例 ID 后面拼接“-node-mongos 节点索引号”可得到对应的 Mongos 节点的 ID,“Mongos 节点索引号”从0开始,最大值为 Mongos 节点个数-1

十八、入参说明

查询云数据库 MongoDB 监控数据,入参取值如下:
&Namespace=QCE/CMONGO
&Instances.N.Dimensions.0.Name=target
&Instances.N.Dimensions.0.Value=视查询维度而定
