I'm using atop to monitor disks usage, network and other load parameters. my problem is, atop will show only the top 3 disks. How can i display all of them? couldn't find anything from man or any docs on the internet.

Well, I'm seeing all 4 of my disks (and the raid array they are in) in atop. Are you sure all of your disks are connected, I guess? – ssmy Mar 20 '13 at 15:59
    
yes i'm sure. i guess you are checking not on production server. when you have lots of process, the bottom windows goes up and shrinks the upper window, that's why it shows max 3 disks – teslasimus Mar 20 '13 at 20:30
    
I have plenty of processes, but the process list doesn't start until the upper window is fully shown: i.imgur.com/869sYBI.png What version of atop? – ssmy Mar 20 '13 at 20:33
    
i have this message at start Number of variable resources limited to fit number of lines Version: 1.26 - 2010/11/17 13:42:37 < gerlof.langeveld@atoptool.nl > – teslasimus Mar 20 '13 at 20:39
    
You must have too many things there for the number of lines. Try writing to a file (atop 1 1 >file) and see if everything you want to see is in there. – ssmy Mar 20 '13 at 21:56
atop -PDSK <interval>

This gives machine parseable output of the following fields, per disk: name, number of milliseconds spent for I/O, number of reads issued, number of sectors transferred for reads, number of writes issued, and number of sectors transferred for write

The command top can display CPU usage, Memory usage, Swap Memory, Cache Size, Buffer Size, Process PID, User, Commands

Try glances CLI curses based monitoring tool instead. It shows all disks. To install glances run:

sudo apt-get install glances
