How do I measure disk I/O ?

[negatory]

I want to know how can I measure disk I/O much like the gnome system monitor applet.I want to measure the disk I/O in real time (so I can know the read/writes at any given moment).
I'm planning to log the information and see the effect it has on temperatures in my system along the day.
Thanks

try netstat 5 , and vmstat 5
you have to write a script file if you want to collect datas...

I think "iostat" is the binary you are looking for.

vmstat is good for the virtual memory manager. Be warned that iostat shows the IO statistics on the per-disk level not the per-process level.

maybe "iotop" is what you're looking for
