HP 3PAR OS 3.1.3 Command Line Interface Reference

Specifies the LD(s) or pattern(s) for which the histogram data is collected.
RESTRICTIONS
None
EXAMPLES
The following example displays one iteration of a histogram of service times for all LDs:
cli% histld –iter 1
12:38:49 10/20/04 ------------Time (millisec)------------
Ldame 0.26 0.53 1.05 2.1 4.2 8.4 17 34 67 135

NOTES
• Each service time histogram column shows the number of accesses with service times between
the time shown in the column's heading to the time shown in the heading of the column to its
right (or infinity for the last column). Unless all columns are shown, the first column shows the
number of accesses with service times less than the heading of the second column.
• Each I/O size histogram column shows the number of accesses with I/O size between the
size shown in the column's heading to the size shown in the heading of the column to its right
(or infinity for the last column).
• If the <LD_name_or_pattern> specifier is used, then logical disks with names that match
any of the patterns are listed, otherwise all LDs are listed. These patterns are glob-style patterns
(see help on sub,globpat).
• Patterns are specified as regular expressions. Refer to “Glob-Style Pattern” (page 12) for further
information. Issuing histld –n LD_name.* displays histogram data for all LDs whose
name begins with LD_name.
