I'd really like to have a way to output the nfsstat counters at regular
intervals (every 3 seconds) where the output is the difference between 3
seconds ago and now. Frequently I'll run a test and want to watch the
nfs call profile throughout the course of the test.
Does something like this already exist?
Are there objections to seeing a feature like this?
I'm thinking something like:
nfsstat --sleep=1
nfs v3 call: Server Client
total: 0 3476
null: 0 0
getattr: 0 1679
setattr: 0 0
lookup: 0 839
access: 0 839
readlink: 0 0
read: 0 0
write: 0 0
create: 0 0
mkdir: 0 0
symlink: 0 0
mknod: 0 0
remove: 0 0
rmdir: 0 0
rename: 0 0
link: 0 0
readdir: 0 0
readdirplus: 0 0
fsstat: 0 119
fsinfo: 0 0
pathconf: 0 0

I wrote some patches a couple of years back to do that. I'll see if I
can dig 'em up.

It seems like everyone has a patch or a script that does this sort of
thing. It'd be great if it was just a part of nfsstat the way that
vmstat, and iostat print differences on a regular basis.
