iostat are great tools to see how much I/O is happening.
But I haven't found out how these (or other) tools can show me the I/O rate per device and per process.
So I'm looking for a way to let
iostat show the specific processes or to let
iotop show the I/O per device when limited to one process. Or another tool that can give me insight into which device is used by a process.
I need this to get a better grip on optimizing MySQL on a box that has Fusion I/O cards but it's still very slow.
