XLOAD(1)            UNIX Programmer's Manual             XLOAD(1)



NAME
     xload - X window system load average display

SYNOPSIS
     xload [ option ] ...

DESCRIPTION
     _x_l_o_a_d continuously displays the system load average under
     the _X window system.  _x_l_o_a_d creates a window in which the
     load average is represented as a bar graph with n divisions.
     Each division represents one unit of load average.  The name
     of the host is displayed in the upper left corner.

     _x_l_o_a_d understands the following options:

     -bd _c_o_l_o_r
             Specify the border color.  On monochrome displays
             this option is ignored.  The default color is
             ``black''.

     -bg _c_o_l_o_r
             Specify the background color.  On monochrome
             displays this option is ignored.  The default color
             is ``white''.

     -bw _p_i_x_e_l_s
             Specify the width in pixels of the border around the
             _x_l_o_a_d window. The default value is 3 pixels.

     -fg _c_o_l_o_r
             Specify the graph color.  On monochrome displays
             this option is ignored.  The default color is
             ``black''.

     -fn _f_o_n_t_n_a_m_e
             The hostname will be displayed in the specified font
             (if none is specified, this defaults to 6x10).

     -hl _c_o_l_o_r
             Specify the hostname and scale line color; the
             default is to make it the same as the graph color.

     -rv     Reverses the default color values (i.e., black
             becomes white and white becomes black).

     -fw     Forces the default color values to remain at their
             predetermined settings (i.e., white is white and
             black is black).

     -scale _i_n_t_e_g_e_r
             Specify the minimum number of divisions on the graph
             (default 1).  _X_l_o_a_d is free to use more divisions if

             the load gets too high to display, but it will never
             use fewer divisions than this.

     -update _s_e_c_o_n_d_s
             Specify the frequency in seconds with which _x_l_o_a_d
             updates its display (except if the _x_l_o_a_d window is
             obscured and then exposed, immediate redisplay
             occurs).  The default update frequency is 5 seconds.
             Specification of a frequency less than 5 seconds is
             ignored and the default frequency is used instead.

     =_g_e_o_m_e_t_r_y
             The load graph window is created with the specified
             size and location determined by the supplied
             geometry specification.  See _X(_1) for a full expla-
             nation.

     [_h_o_s_t]:[_d_i_s_p_l_a_y]
             Normally, _x_l_o_a_d gets the host and display number to
             use from the environment variable ``DISPLAY''.
             Either or both can be specified with this option.
             _h_o_s_t specifies which machine to create the _x_l_o_a_d
             window on, and _d_i_s_p_l_a_y specifies the display number.
             For example, ``mit-grape-nehi:0'' creates an _x_l_o_a_d
             on display 0 on machine mit-grape-nehi. Either value
             can be defaulted by omission but ``:'' is necessary
             to specify one or both.

             display.

     ReverseVideo
             If ``on'', reverse the effect of the defaults
             colors.  Ignored on color displays.

     Scale   Set the minimum scale.

     Update  Set the update interval.

ENVIRONMENT
     DISPLAY - to get the default host and display number.

SEE ALSO
     X(10, xwm(1), X(8C), mem(4), select(2)

DIAGNOSTICS
     Unable to open display or create window. Unable to open
     /dev/kmem.  Unable to query window for dimensions. Various X
     errors.

BUGS
     _x_l_o_a_d requires the ability to open and read /dev/kmem. On
     most systems, this requires the suid bit set with root own-
     ership or the sgid bit set and membership in the same group
     as /dev/kmem.
