- Do CPU utilization for more than one CPU.
- .IP "\fB\-R\fR"
- Display the number of remote processes belonging to this host (in 10's).
- .IP "\fB\-a\fR"
- Display the number of hosts to which this host can migrate (in 10's).
- .IP "\fB\-A \fIavailInterval\fR"

- .SH INTRODUCTION
- This widget displays operating system parameters as a running 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 \fIinterval\fP
- 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.
- .PP
- 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 spritemon 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.
- .PP
- The disk related options only work on machines with disks.
- The \fB\-D\fR option specifies which disk to display
- information about, or \fB-disks\fP can be used to display
- information about all the disks in the system. Utilization is displayed,
- and \fB\-r\fR and \fB\-w\fR are used to display raw read and write counts.
- The number to specify to \fB\-D\fR corresponds to a kernel table entry
- that is indexed starting at zero.
- .SH "BUGS"
- .PP
- The \fB\-i\fR option needs to be glommed together with another option,
- i.e. \fB\-io\fR, or it gets interpreted by the X toolkit and \fBspritemon\fR
- starts out iconic.
- .PP
- The value of the argument to \fB\-D\fR is un-intuitive.
- .PP
- The disk information should display the file system name,
- but kernel support is needed for this.
