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.
There's no accurate one-line solution using the existing nfsstat
commandline, but it should be easy to add.
Something like this sort of works:
watch -n 1 'nfsstat --since /tmp/stats; nfsstat >/tmp/stats', but it
feels more like a workaround than a feature.
It's also slightly inaccurate, since it misses any activity that
happened in the brief time between the two invocations.
Using watch doesn't allow you to see what happened in the past either.
Moving to a listed output format instead of the traditional nfsstat
output (as seen below) makes it trivial with a simple grep to watch the
stats that you really care about and ignore the rest.

Cool. I'll spend some time today then.

I'd really like to have a way to output the nfsstat counters at
regular intervals (every 3 seconds) where the output is the

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
