Hi Kevin-
man watch(1)
What would you watch?
For example:
watch -n3 nfsstat -c
You can also use the "-d" option to highlight the differences between
the current sample and the previous sample.
He was asking for deltas; the above only gives cumulative totals.
In that case, he might try one of the Python scripts I wrote that
report NFS and RPC metrics. mountstats and nfs-iostat are included in
the latest nfs-utils tarball. If they don't do exactly what is
needed, it should be easy to hack them.
There's no accurate one-line solution using the existing nfsstat
commandline, but it should be easy to add.

I'd really like to have a way to output the nfsstat counters at

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
