.SH DESCRIPTION
.I Vismon
monitors use of one or more Unix
.I systems.
It displays time of day, announcements,
and CPU usage statistics.
.PP
CPU usage is reported as a numerical load average (average number
of runnable processes) and its change in the last
minute, and a bar graph showing, left-to-right, the
proportion of CPU time spent in: default-priority user processes,
low priority (nice) processes, system kernel, stream I/O, and idle time.
.PP
Arrival of mail or communications via
.IR wall (8)
or
.IR write (1)
is announced.
Mail announcements include an icon of the sender.
Communications appear in a shell
.RI ( sh (1))
layer superimposed on
.I vismon's
layer.
This layer may be used for reply.
.PP
The options are:
.TP
.BI - n
Update the bar graph every
.I n
seconds.
.RI ( n =5
by default.)
.TP
.BI -m
Do not monitor CPU usage on other systems.
.PP
Button 2 selectively toggles the monitoring of other systems.
The list of systems is obtained from one of the following: 
a file named in the VISMON enviroment variable,
.FR $HOME/lib/vismon ,
or
.FR /usr/jerq/lib/vismon .
.PP
.I Sysmon
is the same as
.I vismon
without icons.
.PP
.I Vwhois
causes a dummy mail announcement from
.I person
to appear in
.I vismon
layers.
