Thật khó cho tôi để nhìn tốt những bức ảnh này, nhưng:
Hãy nhìn vào người đàn ông trên đỉnh:
Tôi tự hỏi nếu cuối cùng bạn đang yêu cầu một điều khác, trong phần CPU bạn có:
Every line contains the percentage of cpu time spent in kernel mode by all
active processes (`sys'), the percentage of cpu time consumed in user mode
(`user') for all active processes (including processes running with a nice
value larger than zero), the percentage of cpu time spent for interrupt
handling (`irq') including softirq, the percentage of unused cpu time while
no processes were waiting for disk-I/O (`idle'), and the percentage of unused
cpu time while at least one process was waiting for disk-I/O (`wait').
In case of per-cpu occupation, the last column shows the cpu number and the
wait percentage (`w') for that cpu. The number of lines showing the per-cpu
occupation can be limited.
Dù sao, bạn có thể đọc số liệu thống kê cụ thể của đĩa:
d Show disk-related output.
When "storage accounting" is active in the kernel, the
following fields are shown: process-id, amount of data read
from disk, amount of data written to disk, amount of data that
was written but has been withdrawn again (WCANCL), disk
occupation percentage and process name.

D
D Sort the current list in the order of disk accesses issued.
The one-but-last column changes to ``DSK''.

RDDSK
RDDSK When the kernel maintains standard io statistics (>= 2.6.20):
The read data transfer issued physically on disk (so reading from
the disk cache is not accounted for).
...
VIẾT
WRDSK When the kernel maintains standard io statistics (>= 2.6.20):
The write data transfer issued physically on disk (so writing to
the disk cache is not accounted for). This counter is maintained
for the application process that writes its data to the cache
(assuming that this data is physically transferred to disk later
on). Notice that disk I/O needed for swapping is not taken into
account.
....
LVM / MDD / DSK
LVM/MDD/DSK
Logical volume/multiple device/disk utilization.
Per active unit one line is produced, sorted on unit activity.
Such line shows the name (e.g. VolGroup00-lvtmp for a logical
volume or sda for a hard disk), the busy percentage i.e. the
portion of time that the unit was busy handling requests
(`busy'), the number of read requests issued (`read'), the
number of write requests issued (`write'), the number of KiBytes
per read (`KiB/r'), the number of KiBytes per write
(`KiB/w'), the number of MiBytes per second throughput for reads
(`MBr/s'), the number of MiBytes per second throughput for
writes (`MBw/s'), the average queue depth (`avq') and the average
number of milliseconds needed by a request (`avio') for seek,
latency and data transfer.
If the screen-width does not allow all of these counters, only a
relevant subset is shown.
The number of lines showing the units can be limited per class
(LVM, MDD or DSK) with the 'l' key or statically (see separate
man-page of atoprc). By specifying the value 0 for a
particular class, no lines will be shown any more for that class.
