iostat

操作概述

获取虚拟存储卷iostat信息

命令参数

-v|--volume-id=string     必要参数，存储卷id，示例：a4ef106e_vs_vol_rep2
-t|--time-frame=string    必要参数，获取所需的时间长度，枚举值：hour, day, week, custom
-S|--storage=integer      如果需要更新存储趋势则置为1，默认为1。枚举值：0, 1
-h|--hitrate=integer      如果需要更新命中率趋势则置为1，默认为1。枚举值：0, 1
-s|--start=string         自定义开始时间，配合--time-frame为 custom 使用。格式：'2025-12-12 12:12:12'
-e|--end=string           自定义结束时间，配合--time-frame为 custom 使用。格式：'2025-12-12 02:12:12'

使用示例

acli storage asan volume iostat -v a4ef106e_vs_vol_rep2 -t custom -S 1 -h 1 -s '2025-12-12 12:12:12' -e '2025-12-12 14:12:12'
