Sometimes I want to know how much I/O a thread is doing, or the process as a whole.
Typically I use Sysinternals process explorer for this (on Windows).
I wat thinking that perhaps Yourkit (using the new Probes feature) could be able to get this data relatively easily.
If so, even per thread/process I/O graphs could be provided (similar to CPU graphs), perhaps even distinguishing between File I/O and Network I/O.
Just an idea for YK10
