Memory utilzation

Mukesh011 — Thu, 27 May 2010 12:02:55 GMT

Hi All ,
I am checking the memory utilization in one server for few user

If you will look at the detail for mora user memory utilization is 1.91697e+07 while for other users it's no e+07 . Could someone explain what is this e+07 ?

vuh777 # UNIX95= ps -eo ruser,pid,args,vsz=Kbytes |grep mora | awk '{ val +=$4} END {print (val)/(1024*1024)}'
1.91697e+07
vuh777 # UNIX95= ps -eo ruser,pid,args,vsz=Kbytes |grep root | awk '{ val +=$4} END {print (val)/(1024*1024)}'
0.180229
vuh777 # UNIX95= ps -eo ruser,pid,args,vsz=Kbytes |grep oracle | awk '{ val +=$4} END {print (val)/(1024*1024)}'
1.76985

Hi

this is just formatting.
use the printf function with appropiate formatting instead.

see any awk manual

This is scientific notation for 10**7, 10 million.

No need for that. Just use:
BEGIN { OFMT="%.0f" }

use kmeminfo to get memory details, which can give more detailed memory details.
