获取性能统计信息

使用 statistics_get 命令可从存储系统检索性能统计信息。

statistics_get [ perf_class=perfClassName | host=HostName | host_iscsi_name=initiatorName |
host_fc_port=WWPN | target=RemoteTarget | remote_fc_port=WWPN | remote_ipaddress=IPAddress |
vol=VolName | domain=DomainName | ipinterface=IPInterfaceName | local_fc_port=ComponentId ]
< start=TimeStamp | end=TimeStamp > [ module=ModuleNumber ] 
count=N interval=IntervalSize resolution_unit=<minute|hour|day|week|month>

参数

名称 类型 描述 必需 缺省值
host 对象名 将统计信息限制为仅特定主机的统计信息。 N 所有主机
host_fc_port 不适用 主机端口的 FC 地址。 N 所有端口。
target 对象名 将统计信息限制为仅由指定远程目标生成的 I/O 的统计信息(由于远程镜像)。 N 所有目标。
remote_fc_port 不适用 将统计信息限制为仅指定主机/远程 FC 端口的统计信息。 N 所有端口。
remote_ipaddress 不适用 远程目标端口的 IP 地址。 N 所有端口。
host_iscsi_name iSCSI 启动器名称 将统计信息限制为仅指定 iSCSI 启动器的统计信息。 N 所有端口。
ipinterface 对象名 将统计信息限制为指定 IP 接口的统计信息(仅与 iSCSI 相关)。 N 所有接口。
module 不适用 将统计信息限制为仅指定指定模块的统计信息。 N 所有模块。
local_fc_port 不适用 将统计信息限制为仅针对指定 FC 端口执行的 I/O 的统计信息。 N 所有端口。
vol 对象名 将统计信息限制为仅指定卷的统计信息。 N 所有卷。
domain 对象名 将统计信息限制为仅指定域的统计信息。 N 所有域。
start 不适用 统计信息报告的起始点。 N 不适用
end 不适用 统计信息报告的结束点。 N 不适用
count 正整数 报告的时间点数。 Y 不适用
interval 正整数 每个统计信息时间点中的时间长度。 此数字的解析在 resolution_unit 中设置。 Y 不适用
resolution_unit 枚举 为每个分箱的长度设置计量单位。 Y 不适用
perf_class 对象名 显示带宽和 IOPS 的性能类汇总统计信息。 N 所有性能类。

此命令列示 I/O 统计信息。 count 参数设置统计信息报告中的行数。 intervalresolution_unit 参数的组合可为每个统计行设置时间长度。 必须提供开始时间戳记或结束时间戳记。 这些时间戳记可设置统计报告的时间。 其他参数可将统计信息限制为特定主机、主机端口、卷、域和接口等的统计信息。

对于每个统计信息行,会报告 48 个数字,用于表示带宽、IOPS 和等待时间的所有 16 个选项的读/写、命中数/未命中数和 I/O 大小报告的所有组合。 统计信息收集限制为 32 个池和 200 个卷。

startend 字段的语法如下所示:Y-M-D[.[h[:m[:s]]]],其中范围如下所示:

  • Y - 年(四位数字)
  • M - 月 (1-12)
  • D - 日 (1-31)
  • h - 小时(0-23,0 为缺省值)
  • m - 小时(0-59,0 为缺省值)
  • s - 秒(0-59,0 为缺省值)

年、月和日将使用短划线分隔,而可选的小时、分钟和秒将使用冒号分隔。

输出单位:
  • 超大型块 >512KB
  • 大型块 - 64-512KB
  • 中等大小的块 - 8-64KB
  • 小型块 - 0-8KB
  • 等待时间(以毫秒为单位)
  • 带宽(以 KB 为单位)
