TLOAD(1) User Commands TLOAD(1)
NAME
tload - graphic representation of system load average
SYNOPSIS
tload [options] [tty]
DESCRIPTION
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).
OPTIONS
-s, --scale number
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.
-d, --delay seconds
The delay sets the delay between graph updates in seconds.
-h, --help
Display this help text.
-V, --version
Display version information and exit.
FILES
/proc/loadavg load average information
SEE ALSO
ps(1), top(1), uptime(1), w(1)
BUGS
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.
