    Monitoring Metrics

    Metric Meaning Description Unit Dimension
    DiskReadIops Disk read IOPS Number of I/O reads from block storage to the memory per second - diskId
    DiskReadTraffic Disk read traffic Rate at which data is read from block storage to the memory KB/s diskId
    DiskWriteIops Disk write IOPS Number of I/O writes from the memory to block storage per second - diskId
    DiskWriteTraffic Disk write traffic Rate at which data is written from the memory to block storage KB/s diskId
    DiskAwait Disk I/O waiting time Percentage of time when the CPU is idle with pending I/O requests ms diskId
    DiskSvctm Disk I/O service time I/O service time ms diskId
    DiskUtil Ratio of busy disk I/O periods Ratio of non-idle time during which I/O operations run on the disk % diskId
    DiskUsage Disk partition usage Percentage of used disk partition capacity to the total capacity % InstanceId

    Note:

    The statistical granularity (period) may vary by metrics. You can obtain the period supported by each metric by calling the DescribeBaseMetrics API.

    Overview of parameters in each dimension

    Parameter Dimension Name Dimension Description Format
    Instances.N.Dimensions.0.Name diskId Dimension name of the block storage instance ID Enter a string-type dimension name, such as diskId
    Instances.N.Dimensions.0.Value diskId ID of the block storage instance Enter a specific instance ID, such as disk-test
    Instances.N.Dimensions.0.Name InstanceId Dimension name of the disk partition instance ID Enter a string-type dimension name, such as InstanceId
    Instances.N.Dimensions.0.Value InstanceId ID of the disk partition instance Enter a specific instance ID, such as ins-mm8bs222

    Input Parameters

    Block storage allows you to query monitoring data with the following two dimensional combinations. The input parameters are as follows:

    1. To query the monitoring data of block storage, configure input parameters as follows:

    &Namespace=QCE/BLOCK_STORAGE
    &Instances.N.Dimensions.0.Name=diskId
    &Instances.N.Dimensions.0.Value=

    2. To query the disk partition usage of the server, configure input parameters as follows:

    &Namespace=QCE/BLOCK_STORAGE
    &Instances.N.Dimensions.0.Name=InstanceId
    &Instances.N.Dimensions.0.Value=
