Monitor I/O activity on hard drive

[tonyfreak215]

I am looking for a program that will get me the breakdown of IO activity for a hard drive.

For example; if there was 100MB of reads/writes, it would give me a breakdown of the IO sizes.

I would like to get an idea of what my database activity is like.

On linux there is iotop and the kernel apis it uses. you may have to tweak the code a bit to get exactly the data you need, but the kernel apis exist.

windows/osx: good luck. if it does exist, it will probably be expensive.
