15.5
InForm OS Version 2.3.1 Command Line Interface Reference
EXAMPLES
The following example displays one iteration of a histogram of service times for system
chunklets:
For the previous example, before the
histch command was issued, the setstatch start
command was issued for chunklets 0 and 1 on logical disks
admin.usr.0, tp–0–sa–0.1,
and tp–0–sa–0.0.
NOTES
■ The setstatch command must be issued to enable statistics collection on chunklets
before issuing the
histch command. See setstatch on page 21.72 for additional
information.
■ 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).
■ 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).
