Hi Max,
A word of caution about building metrics collectors based on debugfs
output: there are no stability guarantees. While the format won't be
changed just for the sake of change of course, expect zero effort to
preserve backwards compatibility.
The latency metrics in particular are sent to the MDS in binary form
and are intended to be consumed through commands like "ceph fs top".
debugfs stuff is there just for an occasional sneak peek (apart from
actual debugging).
Thanks,
Ilya
