Anybody know of any disk rate monitoring software out there that will
monitor disk ios and disk transfer rates on Linux systems? On another
os, I have a monitor program that records the following information:

In particular, I am interested in the number of bytes per second written to
each disk drive (whether they are raided or not). I am looking for
bottlenecks.
I may try to port the software, but am not interested in reinventing the
wheel if anyones knows of monitoring software for Linux that already exists.
Thanks in advance,
Kent Ziebell
