◦ t - Specifies total statistics. ◦ rw - Specifies total read and write statistics. • Specifies the threshold service time in milliseconds. • Specifies the minimum number of access above the threshold service time. When filtering is done, the is compared with the sum of all columns starting with the one which corresponds to the threshold service time. For example,-t,8,100 specifies that only the rows where the 8ms column and all columns to the right adds up to more than 100 are to be displayed. -ni Specifies that histograms for only nonidle devices are displayed. This option is shorthand for the option -filt t,0,0. SPECIFIERS None. RESTRICTIONS None. EXAMPLES The following example displays a histogram of service times for reads and writes to ports: li% histport 12:35:24 10/20/04 Time (millisec Port D/C 0.26 0.53 1.05 2.1 4.2 8.4 17 34 67 135 0:0:1 data 0 0 0 0 0 0 0 0 0 0 0:0:2 data 315 778 2 0 0 0 0 0 0 0 0:1:1 data 0 0 0 5 24 51 25 4 0 0 0:1:2 data 0 0 0 5 27 53 23 1 0 0 1:5:1 data 0 0 0 2 19 38 28 11 0 0 1:5:2 data 0 0 0 5 20 36 29 7 0 0 total data 315 778 2 17 90 178 105 23 0 0 Press the enter key to stop... NOTES • Each service time histogram column shows the number of accesses with service times between the point in time shown in the column's heading to the point in 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). • Previous options -n , -s , and -p have been replaced with -nodes , -slots , and -ports . histport 193
