tload - graphic representation of system load average
tload [options] [tty]
tload prints a graph of the current system load average to the specified tty (or the tty of the tload process if none is specified).
The scale option allows a vertical scale to be specified for the display (in characters between graph ticks); thus, a smaller value represents a larger scale, and vice versa.
The delay sets the delay between graph updates in seconds.

The -d delay option sets the time argument for an alarm(2); if -d 0 is specified, the alarm is set to 0, which will never send the SIGALRM and update the display.
