Hello Friends,
I wanna to ask how to learn disk (read,write) latency on linux server
I use "iostat -kx 5" command to learn latency.
But i cant understand which field show latency, svctm or iowait ?
And if value svctm is gerater than 15 ms can we say there is a slowly io performance ?
And i wanna to learn can we list io latency and utilization for per process?
Thanks.
