[lustre-discuss] How to find out what the OSS interacts with the Lustre client at a given time ?

[Raj]

I prefer to pull them from server side by:

On OSS:
 /proc/fs/lustre/obdfilter/*/exports/CLIENT_IP at FABRIC/stat
snapshot_time             1492265908.551519 secs.usecs
read_bytes                21575 samples [bytes] 458752 1048576 22621818880
statfs                    1 samples [reqs]
preprw                    21575 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 at FABRIC/stat
snapshot_time             1492266510.531256 secs.usecs
open                      3 samples [reqs]
close                     1 samples [reqs]
unlink                    1 samples [reqs]
getattr                   3 samples [reqs]

Thanks
