.SH "DESCRIPTION"
|
|
.PP
|
|
ttyload is a "tty" based load monitoring tool\&. Not entirely unlike
|
|
xload, it plots a graph of a system's "load average" data\&. Unlike
|
|
xload, it uses 3 line graphs to plot things, instead of a single fill
|
|
graph, so that it can show you not only the 1-minute load average, but
|
|
also the 5-minute and 15-minute averages\&. Also unlike xload, it uses
|
|
a basic terminal (tty) to display the information, instead of an X
|
|
window\&. ANSI escape sequences are used (optionally) for colorization
|
|
and screen manipulation\&.
|
|
.PP
|
|
A few of the main features of ttyload are:
|
|
.PP
|
|
.IP o
|
|
graphs load averages (all 3 numbers) over time
|
|
.IP o
|
|
uses ANSI escape sequences to colorize graphs
|
|
.IP o
|
|
works without requiring X11 libraries, in a Terminal window
|
|
.IP o
|
|
automatically determines screen size by default

.SH "USAGE"
|
|
.PP
|
|
The easiest way to use ttyload is just to invoke the command, with no
|
|
additional options\&.
|
|
.PP
|
|
Additional options are described below\&.
|
|
.PP
|
|
To quit ttyload, enter the terminal's interrupt character (typically
|
|
control-C)\&.

.SH "OPTIONS"
|
|
.PP
|
|
ttyload uses standard getopt() style options processing\&.
|
|
Available options are:
|
|
.PP
|
|
|
|
.DS
|
|
|
|
.PP
|
|
.IP "\fB-h\fP"
|
|
Display a brief usage statement ("help")\&.
|
|
.IP "\fB-v\fP"
|
|
show version info, then exit
|
|
.IP "\fB-m\fP"
|
|
monochrome mode (no ANSI escapes)
|
|
.IP "\fB-c <cols>\fP"
|
|
Sets the number of columns wide to make the display
|
|
.IP "\fB-r <rows>\fP"
|
|
Sets the number of rows high to make the display
|
|
(these two options combine to override the default behavior of
|
|
auto-determining screen size)
|
|
.IP "\fB-i <seconds>\fP"
|
|
Alter the number of seconds in the interval between
|
|
refreshes\&. The default is 4, and the minimum is 1, which is silently
|
|
clamped\&.
