FILE SYSTEM USAGE 4

[Ann28]

Hi Everyone -

I am using unix AIX Version 5.2.

What command should I use to see the CPU utilization & how many bytes, % every file in the system is using to see if it needs to be reorganized/resized.


Thanks a lot for your help!
Ann.

Mohmin,

you can try the following commands,they all work:


#vmstat 2 10 % checks virtual mem and cpu status
every 2 sec 10 times.

#iostat 2 10 % checks the cpu and disk activity

#ps -ef |wc -l % to see no: of process running

#ps aux

#sar -u 60 30 %collects cpu usage every 60sec
#topas

bye,

df -k" will get you information about how full the filesystems are.

Thank you Mohmin!

But I need a command to list all files in the system along with the %
df ???

 

[kHz]

du

 

[mohmin]

mohmin,


#lsfs

#lsfs -q (fsname)

#dfsck /filesystem/filesystem



I think i did'nt get ur question,if yes then the above commands should resolve it.

If not let me know....

Bye,

THAKS ALL FOR YOUR HELP!!!
but I really need a command to show all the files under the directory & the usage %

As kHz says, du might be part of the answer. man du for details, but you might need to manipulate it for percentages.

You could use a program called dispus. Its availible on this web site.

I have used it and it helps alot. It was written by Annihilannic. It will tell you file sizes and it will go down the path.

Here is a little script I wrote up to help out some of our SA's in identifying large files within given directories. Please feel free to use and distibute as you see fit. Remeber that if you copy and paste this there may be lines that word wrapped in this forum and need to be recombined when you paste it into your UNIX machine.
