OOPPTTIIOONNSS
--TT _i_n_t_e_r_v_a_l
Sets the interval at which the display is updated.
Default is 5 seconds.
--HH _h_e_i_g_h_t
Sets the height of each graph displayed. Default is 40
pixels.
--uu Display CPU utilization on a scale from 0.0 to 1.0.
--NN _n_u_m _C_P_U_s
Do CPU utilization for more than one CPU.
--RR Display the number of remote processes belonging to
this host (in 10's).
--aa Display the number of hosts to which this host can
migrate (in 10's).
--AA _a_v_a_i_l_I_n_t_e_r_v_a_l
Sets the interval at which the count of available hosts
is updated. Default is 15 seconds.
--ff Display file system cache size.
--vv Display amount of physical memory devoted to user vir-
tual memory.
--%% Display cache size (--ff) or VM size (--vv) as a percentage
of main memory.
--MM Display cache size (--ff) or VM size (--vv) in megabytes.
--pp Display the number of page-ins (in 100's). This is a
sum of text, heap, and stack page-ins.
--PP Display the number of pages written out to swap files
(in 100's).
--ii Display the number of ethernet packets received (in
100's).

--oo Display the number of ethernet packets sent out (in
100's).
--ddiisskkss
Display disk statistics for all disks in the system
(superceeds -D).
--DD _n_u_m
Display disk #_n_u_m utilization on a scale from 0.0 to
1.0.
--rr Display the number of disk read transfers (in 100's).
Use with --DD or --ddiisskkss.
--ww Display the number of disk write transfers (in 100's).
Use with --DD or --ddiisskkss.

This widget displays operating system parameters as a run-
ning graph. It is an X toolkit widget and so it needs to
run under the X window system. This is a ``load widget'',
which displays a value every _i_n_t_e_r_v_a_l seconds, and has a
title but no vertical scale. Instead, horizontal lines are
drawn to represent increments in the native unit of whatever
is being displayed. For some parameters, like percentage of
memory devoted to the file system cache, the displayed value
is always between 0 and 1 so there are no horizontal scale
lines. For the megabytes of filesystem cache there will be
horizontal lines that represent megabytes, for remote
processes there will be horizontal lines to represent 10's
of remote processes, and for paging and network traffic
there will be horizontal lines to represent 100's of events.
The value displayed is truncated to the largest value that
can be displayed without causing the horizontal lines to
completely occupy the display. This value is equal to half
the pane height.
Several system parameters can be viewed at once; the load
meters are organized into a vertical pane with each meter of
equal height. It is best to let spritemon determine its own
geometry at startup (it will use the default pane height
times the number of parameters being displayed), or you can
specify a geometry argument on the command line and spri-
temon will evenly divide the window into panes. Otherwise,
if you drag out a window size, the VPane widget does a poor
job of picking the heights of individual panes.
The disk related options only work on machines with disks.
The --DD option specifies which disk to display information
about, or --ddiisskkss can be used to display information about
all the disks in the system. Utilization is displayed, and
--rr and --ww are used to display raw read and write counts.

The number to specify to --DD corresponds to a kernel table
entry that is indexed starting at zero.

The --ii option needs to be glommed together with another
option, i.e. --iioo, or it gets interpreted by the X toolkit
and sspprriitteemmoonn starts out iconic.
The value of the argument to --DD is un-intuitive.
The disk information should display the file system name,
but kernel support is needed for this.
