XCPUSTATE(1) X Version 11(13 July 1988) XCPUSTATE(1)
NAME
xcpustate - display CPU states (idle, nice, system, kernel) statistics
SYNTAX
xcpustate [-toolkitoption ...] [-count iterations] [-interval seconds]
DESCRIPTION
Xcpustate displays bars showing the percentage of time the CPU spends in
different states.
On a machine running Berkeley Unix, or a derivative (Suns with SunOS,
microVaxen with Ultrix), the bar indicates the proportions of idle, user,
nice, and system time with increasing levels of gray scale (from left to
right)
On a machine running System V Release 4, the bar indicates the
proportions of idle, user, kernel, and io wait time with increasing
levels of gray scale (from left to right)
On an Iris4D, there may be more than one bar, one for each CPU, and each
bar indicates the proportions of idle + wait, user, kernel, sxbrk and
interrupt time for each cpu.
On a Cray X/MP or Y/MP, under Unicos 5.1 or greater, it will display bars
for as many cpus as are configured. The proportions of idle, user and
system time are shown for each cpu.
OPTIONS
Xcpustate accepts all of the standard X Toolkit command line options,
plus:
-count iterations
The number of times it should update the display. Default is
forever.
-interval seconds
the interval in between updates. Default is 1 second.
X DEFAULTS
For xcpustate the available class identifiers are:
XCpustate - the application
Form - enclosing the entire application, and sub-Forms enclosing
Label/Bar pairs.
For xcpustate, the available name identifiers are:
xcpustate - application name
The outer Form is "form".
The Forms enclosing the Label/Bar pairs are "formN", where N is the
index number, starting with the top pair as zero.
Each Label name is the same as the label string.

XCPUSTATE(1) X Version 11(13 July 1988) XCPUSTATE(1)
Each Bar name is "barN".
For xcpustate, the available resources are:
name interval, class Interval
corresponds to the -interval option. Takes an integer value.
name count, class Count
corresponds to the -count argument, also takes and integer value.
NOTES
Xcpustate was designed for a multiprocessor (a Silicon Graphics
Iris4D/240) - it happens to work for conventional BSD uniprocessors. It
is meant to be easy to port, and extend to monitor a wide variety of
statistics.
