recently I ran into some I/O overload problrms on some of our machines and been searching to find thresholds for some metrics like:



avgqu-sz

await

svctm



then i saw this post on stack overflow:
display current I/O



I was wondering if there is any way to find max queue length of my machine so when avgqu-sz is more than that number it means overload occurred?



does queue length depends on RAID?
