The "lfs getstripe /path/to/file" command will tell you which OSTs are used for
each file. Different files will be allocated from different OSTs. By default,
stipe_count = 1, so each file will be on a single OST.

I realize I didn't answer all the questions, so:
1) For a file-system-level view, we use ltop, a handy utility that's in
the LMT package (https://github.com/LLNL/lmt). If you want to pinpoint
OST or MDT tests, you could lock a file/dir to a particular OST/MDT and
then use 'zpool iostat ...' to
Use 'zpool iostat -v ...'. You can review the man page for lots of
options, including latency statistics.

Suddenly our lustre installation become dead slow, copying data from local
source to lustre result around 20MB/sec before it was above 600 MB.
i checked zfs status -xv and (all pool healths are ok)
1) How to check which OSTs are involved during data write operation ?
2) How to check Me
