Weblog entry #2 for neofpo
I recently used Windows Vista and it has a very nice feacure: a top like disk access statistics. I can easily identify what process is using the disk and at what rate. I could manage to easily solve some performance issues on Vista using this tool.
The question is: is there a way Linux kernel export disk access usage per process? All I have seen until now is a system wide value, for a whole block device...
There is the brute force method of course, lsof + find by latest modification / access date... but that's not exactly what I want.
Ah, I know about laptop mode, but I wish to fix the cause of the problem (no more useless disk access).
