Berikut adalah perintah dasar iotop yang dapat anda gunakan:
# iotop
atau
$ sudo iotop
-o, –only
Only show processes or threads actually doing I/O, instead of showing all processes or threads. This can be dynamically toggled by pressing o.
-b, –batch
Turn on non-interactive mode. Useful for logging I/O usage over time.
-n NUM, –iter=NUM
Set the number of iterations before quitting (never quit by default). This is most useful in non-interactive mode.
-d SEC, –delay=SEC
Set the delay between iterations in seconds (1 second by default). Accepts non-integer values such as 1.1 seconds.
-p PID, –pid=PID
A list of processes/threads to monitor (all by default).
-u USER, –user=USER
A list of users to monitor (all by default)
-P, –processes
Only show processes. Normally iotop shows all threads.
-a, –accumulated
Show accumulated I/O instead of bandwidth. In this mode, iotop shows the amount of I/O processes have done since iotop started.
-k, –kilobytes
Use kilobytes instead of a human friendly unit. This mode is useful when scripting the batch mode of iotop. Instead of choosing the most appropriate unit iotop will display all sizes in kilobytes.
-t, –time
Add a timestamp on each line (implies –batch). Each line will be prefixed by the current time.
-q, –quiet
suppress some lines of header (implies –batch). This option can be specified up to three times to remove header lines.
-q column names are only printed on the first iteration,
-qq column names are never printed,
-qqq the I/O summary is never printed.
