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

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

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

open  3 samples [reqs]
close 1 samples [reqs]

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 ?

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
