顯示Volume效能統計資料

貢獻者

「show volume performanceStats」命令會傳回Volume效能的相關資訊。

支援的陣列

此命令適用於任何個別儲存陣列,包括 E4000 , E2700 , E5600 , E2800 , E5700 , EF600 和 EF300 陣列,只要安裝了所有 SMCLI 套件即可。

角色

若要在 E4000 , E2800 , E5700 , EF600 或 EF300 儲存陣列上執行此命令,您必須具有 Storage Admin 或 Storage Monitor 角色。

背景

對於儲存陣列中的每個Volume、此命令會傳回下列資訊:

  • 儲存陣列

  • IOS總容量

  • 讀取%

  • 主要讀取快取命中率

  • 主要寫入快取命中率

  • SSD快取命中率

  • 目前的MB/s

  • 最大MB/s

  • 目前的IOS/s

  • 最大IOS/s

  • 最低IOS/s

  • 平均每秒IOS

  • 最低MB/s

  • 平均每秒MB數

  • 目前IO延遲

  • 最大IO延遲

  • 最低IO延遲

  • 平均IO延遲

語法

show (allVolumes | volume ["volumeName"]
volumes ["volumeName1" ... "volumeNameN"]) performanceStats

參數

參數 說明

《allVolumes》

傳回儲存陣列中所有磁碟區效能統計資料的參數。

《Volume》(Volume)

要擷取資訊的Volume名稱。將磁碟區名稱括在方括弧([])內。如果Volume名稱含有特殊字元或數字、則必須在方括弧內以雙引號("")括住名稱。

《Volume》(Volume)

您要擷取資訊的多個磁碟區名稱。使用下列規則輸入磁碟區名稱:

  • 將所有名稱括在方括弧中([])。

  • 以空格分隔每個名稱。

如果磁碟區名稱有特殊字元或數字、請使用下列規則輸入名稱:

  • 將所有名稱括在方括弧中([])。

  • 將每個名稱括在雙引號("")內。

  • 以空格分隔每個名稱。

附註

在您執行「show volume performanceStat」命令之前、請先執行「show session performanceMonitorInterval'命令和「show session performanceMonitor迭 代」命令、以定義收集統計資料的頻率。

「show volume performanceStat」命令會傳回Volume效能統計資料、如下列範例所示:
