Lustre is transitionning /proc files to /sys per kernel developer requests.
Instead of chasing where these files are located now depending on your Lustre version, 'lctl get_param' is the official way to read them.
This command will figure out where to properly read the files.

Objet : [lustre-discuss] osc and llite stats files are not exported to clients
Dear all,
I am having trouble with lustre monitoring using Ganglia gmond_python_modules
(https://github.com/ganglia/gmond_python_modules/tree/master/lustre).
Upon closer inspections, I found that the stats files in /proc/fs/lustre/osc/*/
and /proc/fs/lustre/llite are missing (among other similar files in these directories).
However, lctl get_param osc.*.stats and lctl get_param llite.*.stats return
parameters and values as you would expect. The stats files are what the
gmond_python_modules wants hence the problem monitoring with Ganglia.
After many searching around, could not figure out what I could have done to
have stats export normally to clients and remounting did not help. On MDS and OSS,
I can see the obdfiler/*/export/*/stats or mdt/*/export/*/stats
The lustre manual also said that the exporting of these info to client should be by
default.
Thank you in advance.
Cheers,
Utane
