Question

Cloud server begin generate big disk read/write operation. I want find some script who generate top file with process(process name | TOTAL | READ | WRITE )

Answer 1

You can use iotop to see the reads and writes of each process using a top like interface.

Another way is to look at the /proc/[PID]/io files.

Example:

$ cat /proc/1944/io
read_bytes: 17961091072
write_bytes: 8192000
cancelled_write_bytes: 32768
