显示卷性能统计信息

show volume performanceStats 命令可返回有关卷性能的信息。

受支持的阵列​

此命令适用于单个 DE2000H、DE4000H、DE4000F、DE6000H 或 DE6000F 存储阵列。

角色​

要对存储阵列执行此命令，必须具有存储管理员或存储监察员角色。

上下文​

对于存储阵列中的每个卷，此命令可返回以下信息：

  • 存储阵列

  • 总 IO/秒

  • 读取百分比

  • 主要读取缓存命中（%）

  • 主要写入高速缓存命中（%）

  • 固态硬盘高速缓存命中（%）

  • 当前 MB/秒

  • 最大 MB/秒

  • 当前 IO/秒

  • 最大 IO/秒

  • 最小 IO/秒

  • 平均 IO/秒

  • 最小 MB/秒

  • 平均 MB/秒

  • 当前 IO 延迟

  • 最大 IO 延迟

  • 最小 IO 延迟

  • 平均 IO 延迟

语法​

show (allVolumes | volume ["<var id="GUID-1A331840-A3E0-481F-B1D3-516D777E0B0D__V1111763" className="keyword varname">volumeName</var>"] 
volumes ["<var id="GUID-1A331840-A3E0-481F-B1D3-516D777E0B0D__V1111764" className="keyword varname">volumeName1</var>" ... "<var id="GUID-1A331840-A3E0-481F-B1D3-516D777E0B0D__V1111765" className="keyword varname">volumeNameN</var>"]) performanceStats

参数​

参数描述
allVolumes 该参数可返回关于存储阵列中所有卷的性能统计信息。
volume

要检索信息的卷的名称。将卷名称用方括号（[ ]）括起来。如果卷名称中包含特殊字符或数字，必须在方括号里用双引号（" "）将名称括起来。

volumes

要检索信息的多个卷的名称。使用这些规则输入卷的名称：

  • 将所有名称用方括号（[ ]）括起来。

  • 用空格将每个名称隔开。

如果卷名称包含特殊字符或数字，请使用这些规则输入名称：

  • 将所有名称用方括号（[ ]）括起来。

  • 用双引号（" "）将每个名称括起来。

  • 用空格将每个名称隔开。

注释​

在运行 show volume performanceStat 命令之前，运行 set session performanceMonitorInterval 命令和 set session performanceMonitorIterations 命令可定义收集统计信息的频率。

show volume performanceStat 命令可返回卷性能统计信息，如以下示例中所示：
