tload

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.

AUTHORS

       Branko Lankester, David Engel <david@ods.com>, and Michael K. Johnson <johnsonm@redhat.com>.

REPORTING BUGS

       Please send bug reports to <procps@freelists.org>
