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.

...an't find anything on the net that would explain where the problem is. /proc/cpuinfo shows two cores, but top and /proc/stat show basically one core working: - top shows cpu0 idle constantly at 0%, and sporadic 100%sy or 50%sy 50%us, which can't be right - /proc/stat shows cpu0 idle and iowat at 0 - Munin CPU graph shows 200% available but metrics go only up to 100% - mpstat -P ALL shows proper %idle for both cores, but still core0 gets either 100%sy or 50%sy 50%us sporadically. I've also got this in the logs, possibly due to BIOS, and I don't know if it is related, I've...
