You can also use the utility Glance to get a comprehensive output.

swapinfo -ta

Look in man page for details.

hi,

if yoyu hane need more infos than memory try " sar" for example sar -d 2 10 indicates activity of disks ( every 2 seconds , 10 times) or sar -u 2 10 for processor (-Mu for multi processors)

[amithp]

swapinfo and vmstat give output regarding virtual memory and swap i need outpu regarding memory

[Joel Girot]

please try this little script :

#!/bin/sh
# memtop - show top memory users and pid
# VSZ is in KB
echo " VSZ(KB) PID USER COMMAND"
UNIX95= ps -e -o 'vsz pid ruser args' |sort -nr|head -30

Hi,

You can use several tools to check the memory of your system. The following tools can be used.
(1) sar -u (gives cpu utilization)
(2) top -s2 -d5 (five screens in 2 sec interval)
(3) Glance /Glanceplus

can be used..there are performance monitoring tools as well like
(1) MeasureWare
(2) PerfWare
etc.

Thanks.
