Hi!
I'm not a UNIX fanatic but I like using it for the
Oracle database since it's not stable in the Windows NT
environment (what is?).

Problem: Is there any command to show me the amount
of installed physical-memory in the machine? Is
there some other way to show the processes which uses the
most CPU etc? All together: Does UNIX a an equivalence
to the Windows NT Task Manager?

/Charlie

xsysinfo

XSYSINFO(1x)							 Debian GNU/Linux						      XSYSINFO(1x)

NAME

       xsysinfo - Display Linux kernel parameters in graphical form

SYNOPSIS

       xsysinfo [-help] [-update n] [-[no]title] [-[no]labels] [-[no]loadavg] [-[no]load] [-[no]mem] [-[no]swap] [-[no]smp]

DESCRIPTION

       Xsysinfo  is  an  X application to display some Linux kernel parameters in graphical form. It is like a mix of top, free and xload with the
       difference that the values are shown in form of a horizontal bar. The displayed values are: CPU load average, CPU  load,  memory  and  swap
       sizes (details see below).

OPTIONS

       -update n
	      Set update rate to n milli-seconds

       -title Show title string

       -notitle
	      Don't show title string

       -labels
	      Show gauge labels

       -nolabels
	      Don't show gauge labels

       -loadavg
	      Show CPU load average value

       -noloadavg
	      Don't show CPU load average value

       -load  Show CPU load value

       -noload
	      Don't show CPU load value

       -smp   Show separate SMP loads

       -nosmp Don't show separate SMP loads.

       -mem   Show memory info

       -nomem Don't show memory info

       -swap  Show swap info

       -noswap
	      Don't show swap info

       -help  Display options

DISPLAY

       Xsysinfo display the following values:

       CPU load average
	      CPU load average between 0.000-8.000. The gauge's bar is subdivided into segments, where one segment represents a load value of 1.0.
	      The bar's full length is automatically scaled, depending on the displayed value.

       CPU load
	      percentage CPU load time to CPU idle time subdivided in three segments: user load, system load and nice load. On an SMP  system  the
	      -smp option replaces the single total load meter with a separate meter for each processor.

       Memory The  memory  gauge's  bar is subdivided into two segments with the amount of physical memory, which is used by processes on the left
	      and physical memory used for the page and buffer cache on the right. The length of the whole bar, which is the sum of these two val-
	      ues, shows the amount of physical memory currently used by the system.

       Swap   The percentage of swap space used by the system to total amount of swap space.
