Thanks for answer
I'm already using it.
However, this stats does not mean to understand how much data EACH
lustre client transmits/receives and this stats does not give a name to
the lustre clients (hostname server with client lustre).
I need to get a source-receiver (lustre client - xmt/rcv - oss ) to more
accurately identify the amount of traffic from EACH client of lustre.
I need to get statistics for each lustre client per second.
Thanks for your time

I prefer to pull them from server side by:
On OSS:
/proc/fs/lustre/obdfilter/*/exports/CLIENT_IP@FABRIC/stat
snapshot_time 1492265908.551519 secs.usecs
read_bytes21575 samples [bytes] 458752 1048576 22621818880
statfs1 samples [reqs]
preprw21575 samples [reqs]
commitrw 21575 samples [reqs]
ping 1 samples [reqs]
You can clear the stat (echo clear > stat) and then read at sample
intervals.
Same on MDS node:
/proc/fs/lustre/mdt/*/exports/CLIENT_IP@FABRIC/stat
snapshot_time 1492266510.531256 secs.usecs
open 3 samples [reqs]
close 1 samples [reqs]
unlink1 samples [reqs]
getattr 3 samples [reqs]
Thanks

How to find out what the OSS interacts with the Lustre client at a
given
time?
Maybe it know from /proc/fs/lustre the lustre client or something
else ?
Is it possible to obtain such statistics from MDS, OSS or from a
lustre
client host ?
thanks for you time
