Parameters
Parameter Description
performanceReadCache The alphanumeric identifier (including - and _) of the

Read Cache name contains special characters or consists
only of numbers, you also must enclose the identifier in
double quotation marks (" ") inside square brackets.
file
The file path and the file name to which you want to
save the performance modeling data. Enclose the file
name in double quotation marks (" "). For example:
file="C:\Program
Files\CLI\logs\performance.csv " The default name of
the file that contains the performance modeling data is
readLinkStatus.csv. You can use any file name, but you
must use the
.csv
extension.
Notes
This command returns the performance modeling information similar to this example. The size of your
monitor determines how the information wraps and will affect how the information appears.
