Obtain iostat information of virtual datastore

Command Parameters

-v|--volume-id=string     Required parameter, Datastore ID, Example: a4ef106e_vs_vol_rep2
-t|--time-frame=string    Required parameter, Obtain the required time length, Enumeration values: hour, day, week, custom
-S|--storage=integer      To update storage capacity changes, set this parameter to 1, Default value: 1. Enumeration values: 0, 1, Enum values: 0,1, Default: 1
-h|--hitrate=integer      To update the hit rate trend, set the parameter to 1, Default value: 1. Enumeration values: 0, 1, Default: 1
-s|--start=string         Custom start time, to be used with the --time-frame parameter set to custom, Example: 2025-12-12 12:12:12
-e|--end=string           Custom end time, to be used with the --time-frame parameter set to custom, Example: 2025-12-12 02:12:12
