Is there version of ltop working with lustre 2.10.2 ?

lmtmetric does not work on mds; it is OK checking ost on oss.

# lmtmetric -m mdt
lmtmetric: error reading lustre MDS uuid from proc: Invalid argument
lmtmetric: mdt metric: Invalid argument

I suspect it is due to lmtmetric constantly reading  /proc/fs/lustre/version and it is now in /sys/...

I'm trying to get ltop working on SLF 7.4 with lustre 2.10.2. No need for lmt & DB.
