Debian Medium Disk Read/Disk Write Queue

Question

linux

Good day to all.

Tell me if it is possible to somehow calculate the average disk read queue / average disk write queue in debian (writing and reading are of interest as separate numbers). I tried to google for a long time, but from the results I came across only iostat (which does not display these parameters, or I don’t know) and /proc/diskstat (I didn’t find it either).

I would really appreciate a solution, thanks in advance!

Answer 1

Average turn for what period of time? Take data from the right place with the required frequency, write somewhere and then calculate the average value as simple arithmetic for the desired period of time.

Answer 2

Try atop. A daemon that collects statistics. There are tools to view the accumulated/current data. Where to store logs, for how many days - everything is insisted.
