Thanks a lot Cliff. It seems that IML is not readily available for download, we may need
to go with Intel on this.
Thanks,

Hi,
IOPS on the OSTs? Your OSTs should probably be optimized for capacity and throughput, not
IOPS.
Nevertheless, how about Intel Manager for Lustre*, inside Intel Enterprise Edition of
Lustre*?
Others tools include Collectl, LMT, or "llstat" - the last of these is already
on your OSS's.

Hello,
Can someone please suggest some tools to collect performance numbers like IOPS on OSTs
while running load from Lustre Clients?
First, the standard *nix tools, such as iostat and vmstat should be fine on the OSS nodes,
depending on how LUNs map to OSTs.
Lctl get_param obdfilter.*.brw_stats will also supply much useful information although not
IOPS directly.
Llstat will likely not show you much for IOPS, but again will supply some data.
Collectctl is very scriptable, command line style. LMT and IML are GUI tools and quite
featurefull .
Cliffw
