That's exactly what I did, finally.

So, from what I've seen in the MIB, the current SNMP module mainly
report version numbers and free space information.
I think it would also be useful to get "activity metrics", the same kind
of information which is in /proc/fs/lustre/llite/*/stats on clients (so
we can see reads/writes and fs operations rates),
in /proc/fs/lustre/obdfilter/*/stats on OSSes and
in /proc/fs/lustre/mds/*/stats on MDSes.
Actually, all the /proc/fs/lustre/*/**/stats could be useful, but I
guess what precise metric is the most useful heavily depends on what
you want to see. :)
Cheers,
