Mass storage total read/write and per interval read/write counters
/sys/block/sda/stat and the likes contains a list of very nice counters. They are user readable.
Field 3 and 7 are read/write counters in 512 byte sectors.
- Would be nice to see them as
$7*512as total read and write counters, e.g. Total Read Bytes, Total Write Bytes
- Would be nice to see the difference in measurements for each interval, e.g. Interval Read Bytes, Interval Write Bytes.
- Would be nice to allow the user to select the unit, e.g. instead of showing bytes, allow to use kilo/mega/gigabytes (e.g. in 1000, 1 000 000, 1 000 000 000) but that will also require to allow to specify the precision.
