Anna, there was a client-side file heat mechanism added a few years ago, but I don't know if it is fully functional today.
lctl get_param llite.*.*heat* llite.myth-ffff979380fc1800.file_heat=1 llite.myth-ffff979380fc1800.heat_decay_percentage=80 llite.myth-ffff979380fc1800.heat_period_second=60 And then "lfs heat_get <file>" to dump the file heat, it there haven't been any good tools developed yet to list top heat files.
