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.
