Display the volume entropy recent daily stats

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description

The security anti-ransomware volume entropy-stat show-recent-daily-stat command displays the percentage of data classified as encrypted using an entropy algorithm measured at daily intervals, at the volume level.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-vserver <vserver name>] - Vserver Name

This parameter specifies the Vserver of the anti-ransomware enabled volume for which the entropy stats need to be displayed. If this parameter is specified, the command displays entropy stats only for the specified Vserver.

[-volume <volume name>] - Volume Name

This parameter specifies the anti-ransomware enabled volume for which the entropy stats need to be displayed. If this parameter is specified, the command displays entropy stats only for the specified Volume.

[-timestamp <MM/DD/YYYY HH:MM:SS>] - Start Time

This parameter specifies the start time of entropy stats collection interval. If this parameter is specified, only rows that match the specified input for timestamp will be displayed.

[-total-data-written {<integer>[KB|MB|GB|TB|PB]}] - Total Data Blocks written

This parameter specifies the amount of data written in the interval. If this parameter is specified, only rows that match the specified input for total-data-written will be displayed.

[-encryption-percentage <percent>] - Encryption Percentage

This parameter specifies the encryption percentage of the interval. If this parameter is specified, only rows that match the specified input for encryption-percentage will be displayed.

[-duration <time_interval>] - Duration of the interval

This parameter specifies the duration of the interval. If this parameter is specified, only rows that match the specified input for duration will be displayed.
