I already did and it does the job just fine. Thank you for your kind
suggestion.

Hi,
see the seeksize script on this URL:

Not used it but looks neat!
cheers Andy.

Hi all,
I'd like to ask whether there is a way to monitor disk seeks. I have an
application where many concurrent readers (>50) sequentially read a
large dataset (>10T) at a fairly low speed (8-10 Mbit/s). I can monitor
read/write ops using iostat, but that doesn't tell me how contiguous the
data
