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 tp-0-sa-0.0 0 0 0 0 0 0 0 0 0 0 tp-0-sd-0.1 0 0 0 0 0 0 0 0 0 0 tp-0-sd-0.0 0 0 0 0 0 0 0 0 0 0 admin.usr.0 0 0 0 0 1 6 6 1 0 0 tp-0-sa-0.1 0 0 0 0 0 0 0 0 0 0 tp-0-sd-0.3 0 0 0 0 0 0 0 0 0 0 tp-0-sd-0.2 0 0 0 0 0 0 0 0 0 0 total 0 0 0 0 1 6 6 1 0 0 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 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. histld 185
