I am building some monitoring scripts of our lustre setup and I am having trouble wrapping
my head around:
/proc/fs/lustre/obdfilter/scratch-OST0000/stats
read_bytes 100195530 samples [bytes] 0 1048576 54085118202030
write_bytes 178494565 samples [bytes] 1 1048576 166914498969357
What do each of the each of the numbers mean?

This is similar to all "stats" counters.
The first number is the number of times (samples) the OST has handled a read or write,
second number is the minimum read/write size, third is maximum read/write size, fourth is
the sum of all the read/write requests.
You can work out the average request size by avg = sum / samples.
Cheers, Andreas
