-timecols <fcol> <lcol>
For the I/O time histogram, shows the columns from the first column (<fcol>) through the last
column (<lcol>). The available columns range from 0 through 31.
•
<fcol> must be equal to or greater than 0. The default value of <fcol> is 6.
•
<lcol> must be:
greater than <fcol> ◦
◦ less than or equal to 31
The default value of <lcol> 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 <col>[,<dir>][:<col>[,<dir>]...]
Sorts command output based on column number (<col>). 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 (<dir>):
•
inc - Sort in increasing order (the default).
•
dec - Sort in decreasing order.
-filt <fspec>
Specifies that histograms below the threshold specified by the <fspec> argument are not
displayed. To specify the <fspec> argument, use the syntax: <op>,<val_ms>,<count>.
•
<op> - The<op> argument can be:
•
<val_ms> - Specifies the threshold service time in milliseconds.
•
<count> - Specifies the minimum number of times the service time is above the threshold
service time. When filtering is done, the <count> 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
<VV_name|pattern>...
Displays statistics only for the specified virtual volume or volume name pattern. Multiple volumes
or patterns can be repeated (for example, <VV_name> <VV_name>...). 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:
# histrcvv -vvsum -sync
