Hi Steve-
As promised, here are the Python scripts that I've implemented for analyzing
NFS and RPC performance metrics reported via /proc/self/mountstats. They
still need man pages and proper installation in the nfs-utils Makefile.
While we decide whether to install and support these scripts as they are, or
to replace them with C language re-implementations, let's include them in
nfs-utils now so folks can try them out, bugs can be addressed, and missing
features provided.

NFS iostats - add RDMA statistics

By the way. I love these scripts. The best thing about them is the
way they actually analyze the realtime performance of each RPC
procedure and server mount point including latencies and queuing,
which are nearly impossible to figure out with the commandline.
For example, they instantly tell whether the RPC slot table is too
small (or large) for the workload.
Tom.

Thanks!
I'm hoping that including these in nfs-utils will help polish them a
bit so that more people can understand and use them effectively.
Steve mentioned something at Connectathon about interns and man
pages... ;-)
