DESCRIPTION

       loadmeter is a utility to monitor various system resources. It runs (currently) under Linux  and  Solaris
       systems running the X Window System. It displays information about system hostname, load average, uptime,
       disk  usage  and  memory  information.   loadmeter  uses  the  /proc  filesystem  to  gather most of this
       information under Linux, and under Solaris it reads kernel symbols (What a  headache!).   In  its  normal
       state  it  displays a window with a coloured bar graph showing the load average for the past minute. This
       is also shown in digits at the top of the window. Both are updated every second. A red  notch  marks  the
       maximum load since loadmeter was started, and can be reset by pressing Button2 or hidden with Button3.  A
       blue notch shows the 5 minute load average.

       By  clicking with Button1, a pop-up window appears showing the uptime, the load average for the past 1, 5
       and 15 minutes, the capacity of each filesystem, and memory/swap usage. More detailed information on each
       filesystem is available by highlighting  the  corresponding  one.  The  way  this  window  pops  down  is
       intentional, just to make it interesting. :) (Can be disabled with -noshrink).

       Any  filesystems  with  higher  usage  than  specified by the -warn option (default 90%) are shown with a
       (default) green background in the popup menu. If the -disk option is specified, the text  'disk'  appears
       on the main window if the usage of any filesystem exceeds the value given by -warn, or 90% if that option
       is  not  supplied.  Popping  up  the  stats  window  causes this message to go away, until either another
       filesystem exceeds this value, or the usage of the filesystem that filled falls below the  warning  value
       and then subsequently exceeds it.

       Press Escape within the top level window to exit.

       The following bindings are in effect if either the -override or -parent options is specified.

       Ctrl-button1 lowers the window (-override only).

       Ctrl-button2 raises and moves the window.

       Ctrl-button3 raises and resizes the window.

       A SIGUSR1 sent to the loadmeter process will also raise the top level window. This can be used to raise a
       window that has been obscured by a parent that was specified with the -parent option.

OPTIONS

       The following options are available. They may be abbreviated so long as ambiguity is not reached.

       -display dpy
             Specifies  which  X  server  to  connect  to. If unspecified, the value of the environment variable
             DISPLAY is used.

       -geometry geometry
             Sets the initial geometry of the top level window, given in standard XxY+W+H format. The default is
             40x100.

       -name name
             The name of the application to present to the window manager.

       -numfont font
             Use the specified font for the load average digits on the top level window. The  default  is  6x10.
             Rastermans nexus font is highly recommended.

       -labelfont font
             Use   the   specified  font  for  the  label  displayed  behind  the  bar  graph.  The  default  is
             -schumacher-clean-medium-r-*-*-7-*-*-*-*-*-*-*.

       -label label
             Specify the string to be displayed behind the bar graph. The  default  is  the  hostname  given  by
             uname(2).

       -popupfont font
             Use    the    specified    font   for   the   text   in   the   popup   menus.   The   default   is
             -misc-fixed-medium-r-*-*-10-*-*-*-*-*-*-*.

       -popupbg colour
             Sets the background colour of the popup menus. Default is grey30.

       -popupfg colour
             Sets the foreground colour of the popup menus. Default is yellow.

       -warn percent
             Causes the menu entry for a particular filesystem to be highlighted if the usage for it is  greater
             than the given percentage. The default is 90%.

       -warnbg colour
             Specify the colour to use for highlighting a filesystem whose usage is greater than or equal to 90%
             or whichever is specified with the -warn option. The default is seagreen4.

       -meter colour
             Specify  the  colour  to  use for the bar in the graphical representation of filesystem usages. The
             default is black.

       -override
             Causes loadmeter to set the override_redirect bit on the top level window. This will then cause  it
             to  bypass the window manager and display itself undecorated on the root window. This is useful for
             using it with window managers such  as  Enlightenment  (to  DR  0.13  at  least)  which  insist  on
             decorating  all  top level windows. With this option set, the built in move and resize features are
             enabled.

       -sync Causes loadmeter to call sync(2) each time it checks the disk usages. This can slow things down  on
             systems with busy filesystems, but is more accurate as the filesystems are properly synced.

       -bh height
             Specify the height in pixels of each of the bars (blocks) in the main bar graph. The default is two
             pixels.

       -parent window
             This  option  allows  you to specify a particular window for loadmeter to use as its parent window.
             Normally loadmeter will attempt to map itself onto the root window, however there may be times when
             you wish to map it as a child of another window on the screen. The author uses this to map  several
             instances of loadmeter onto an xclock window, making it easy to move the bank around by just moving
             the xclock window. It's left as an exercise to the reader to think of other uses for this option.

       -disk Causes a warning message on the top level window to be given when the usage of a filesystem exceeds
             90%,  or the value given by -warn.  The warning goes away when the stats window is popped up, until
             either another filesystem's usage is excessive or the usage  of  the  filesystem  that  caused  the
             warning falls below the threshold and then subsequently exceeds it.

       -noshrink
             Disables  the  slow-popdown  eye  candy feature of the stats window. This option is useful for slow
             network connections to the display and/or when  there  is  a  large  number  of  filesystems  being
             monitored.

       -nogeom
             Disables  the  displaying of the window geometry in the cursor as the main window is being moved or
             resized.

       Note that -override and -parent cannot both be given in the same instance.

RESOURCES

       loadmeter reads the X server database for several resources that can be used to specify options  for  all
       instances  of  loadmeter running on the display. The resources have the same names as each of the command
       line options, thus there is no point specifying them here again.

       Boolean options (i.e. those that don't take  an  argument)  are  enabled  by  setting  the  corresponding
       resource to True.

LICENSE

       loadmeter is covered by the GNU General Public License (GPL).

BUGS

       loadmeter does no checking as to whether a colour was successfully allocated by the X server.

       Memory info in Solaris isn't particularly correct. Patches for this would be appreciated...
