Hello,
is there any NFSv4 monitoring tool, that can be run on NFSv4 server (running
NFSv4.0 + GSS) and that reports statistics per connected client? I would like
to see amount of transfered data for each client, latency of RPC calls, rate
of requests.
nfsstat on server does not distinguish individual clients.
nfswatch does not support NFSv4
I didn't find anything else. Do I need to create the tool by myself or is
there free of paid tool thad does the job?

We don't gather such statistics, unfortunately. I agree that it would
be useful, and would be happy to talk about possible implementations

so we decided to implement this using systemtap tool and it works ok. But if
NFS server could provide statistics by itself, it would be far better.

Sure. If you have a detailed description of the statistics that you're
gathering (and/or the systemtap scripts), that could help make sure we
capture what you need.
