-timecols
For the I/O time histogram, shows the columns from the first column () through the last
column (). The available columns range from 0 through 31.
•
must be equal to or greater than 0. The default value of is 6.
•
must be:
greater than ◦
◦ less than or equal to 31
The default value of is 15.
-pct
Shows the number of times the service time appears in each bucket as a percentage. If this
option is not specified, the histogram shows the service times.
-prev
Specifies that the histogram displays data from a previous sample.
–sortcol [,
Sorts command output based on column number (). Columns are numbered from left to
right, beginning with 0. You must specify a column number.
In addition, you can specify the direction of sorting (
inc - Sort in increasing order (the default).
•
dec - Sort in decreasing order.
-filt
Specifies that histograms below the threshold specified by the argument are not
displayed. To specify the argument, use the syntax: ,,.
•
- The argument can be:
•
- Specifies the threshold service time in milliseconds.
•
- Specifies the minimum number of times the service time is above the threshold
service time. When filtering is done, the is compared with the sum of all columns,
starting with the one that corresponds to the threshold service time.
For example, -filt t,8,100 specifies that the display should include only the rows where
the 8ms column and each subsequent column to the right adds up to more than 100.
-ni
Displays histograms for all non-idle devices. This option is shorthand for the option -filt
t,0,0
.
SPECIFIERS
...
Displays statistics only for the specified virtual volume or volume name pattern. Multiple volumes
or patterns can be repeated (for example, ...). If not specified, all
virtual volumes that are configured for Remote Copy are listed.
RESTRICTIONS
None.
EXAMPLES
The following example shows histogram sums for all synchronous Remote Copy volumes:
