MOSMON(1)                 BSD General Commands Manual                MOSMON(1)

NAME
     mosmon -- openMosix load(7,n) monitor

SYNOPSIS
     mosmon [-v | -w] [-t] [-d]

DESCRIPTION
     mosmon displays a bar-chart, normally showing the loads on the various
     openMosix nodes.  Alternatively, it can display the various processor
     speeds, or the amount of available vs. total memory.

     The following options are available:

     -v   Select vertical numbering.  This allows the load(7,n) of more nodes to be
          displayed at any one time.

     -w   Select horizontal numbering.  Although this allows the load(7,n) of less(1,3)
          nodes to be displayed at any one time(1,2,n), it visually looks better.

     -t   Display the count of operational nodes.

     -d   Display also dead (not responding) nodes.

     While in(1,8) mosmon, the following keys may be used:

     h      bring up a help screen.

     Enter  redraw the screen.

     v      select(2,7,2 select_tut) vertical numbering.

     w      select(2,7,2 select_tut) horizontal numbering.

     a      select(2,7,2 select_tut) automatic numbering.  Vertical numbering will be selected
            if(3,n) it would make the difference between being able to simultane-
            ously view the loads of all nodes or not.  Otherwise, horizontal
            numbering is selected.

     s      display processor-speeds instead of loads.
            10000 units(1,7) represent one Pentium-2 at 400 MHz.
            For SMP nodes, this option also displays the number of nodes.

     m      display logically-used vs. total memory: the used memory is dis-
            played as a solid bar while the total memory is extended with '+'
            signs.  The memory is shown in(1,8) megabytes.

     r      display raw-used (non-free) memory vs. total memory: the used mem-
            ory is displayed as a solid bar while the total memory is extended
            with '+' signs.  The memory is shown in(1,8) megabytes.

     u      display processor utilizability percentage.  This means how much
            of the time(1,2,n) either the node is serving some process, or there are
            no processes on that node waiting for swapped-pages.  Under normal
            operating conditions, utilizability should be 100%, dropping only
            when the memory is under pressure.

     l      display loads again.

     d      display also dead (not-responding) nodes.

     D      stop displaying dead nodes.

     t      toggle displaying the count of operational nodes.

     y      display the yardstick: this is the speed of the most typical pro-
            cessor in(1,8) the openMosix cluster, 10000 units(1,7) representing one Pen-
            tium-2 at 400 MHz.  Under normal conditions, the load(7,n) caused by
            one 'number-crunching' process running on a single processor whose
            speed is the yardstick will be displayed as 1.  A similar process
            running on a faster processor and/or an SMP, will show a load(7,n) of
            less(1,3) than 1, and on a slower processor, more than 1.

     Right-Arrow
            move(3x,7,3x curs_move) one node to the right (when not all nodes fit on the screen).

     Left-Arrow
            move(3x,7,3x curs_move) one node to the left (when not all nodes fit on the screen).

     n      move(3x,7,3x curs_move) one screen to the right (when not all nodes fit on one
            screen).

     p      move(3x,7,3x curs_move) one screen to the left (when not all nodes fit on one
            screen).

     q      Quit mosmon.
