.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\&.

|

.Nm
|
||||
is a
|
||||
.Dq tty
|
||||
based load monitoring tool.
|
||||
Not entirely unlike xload, it plots a graph of a system's
|
||||
.Dq 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
|
||||
.Pq tty
|
||||
to display the information, instead of an X window.
|
||||
ANSI escape sequences are used
|
||||
.Pq optionally
|
||||
for colorization and screen manipulation.
|
||||

|

The easiest way to use ttyload is just to invoke the command, with no

||||
additional options\&.
|

.PP
|

Additional options are described below\&.
|

To quit ttyload, enter the terminal's interrupt character (typically

control-C)\&.

.IP "\fB-r <rows>\fP"

auto-determining screen size)
