一、命名空间
Namespace=QCE/BLOCK_STORAGE
二、监控指标
注意：说明：
注意：如需拉取磁盘利用率指标监控数据请参见 云服务器监控指标-磁盘监控。
| 指标英文名 | 指标中文名 | 指标说明 | 单位 | 维度 | 统计规则[period, statType] |
| DiskReadTraffic | 磁盘读流量 | 硬盘每秒读流量 | KB/s | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
| DiskWriteTraffic | 磁盘写流量 | 硬盘每秒写流量 | KB/s | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
| DiskReadIops | 磁盘分区平均每秒读次数 | 硬盘每秒的读次数 | 次 | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
| DiskWriteIops | 磁盘分区平均每秒写次数 | 硬盘每秒的写次数 | 次 | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
| DiskAwait | 磁盘操作等待时间 | 硬盘 IO 等待时间 | ms | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
| DiskSvctm | 磁盘分区平均每次 I/O 操作所花的时间 | 硬盘 IO 服务时间 | ms | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
| DiskUtil | 磁盘分区有 IO 操作的时间与总时间的百分比 | 硬盘 IO 繁忙比率 | % | diskId | [10s, last] [60s, avg] [300s, avg] [3600s, avg] [86400s, avg] |
注意：说明：
注意：每个指标的统计粒度（Period）可取值不一定相同，可通过 DescribeBaseMetrics 接口获取每个指标支持的统计粒度。
三、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 | diskId | 云硬盘 ID 的维度名称 | 输入 String 类型维度名称：diskId |
| Instances.N.Dimensions.0.Value | diskId | 云硬盘的具体 ID | 输入实例具体 ID，例如：disk-test |
四、查询云硬盘监控数据，入参取值如下：
&Namespace = QCE/BLOCK_STORAGE
&Instances.N.Dimensions.0.Name = diskId
&Instances.N.Dimensions.0.Value = 云硬盘 ID
