Probably so, but those scripts are a bit hard to find, aren't they?
We should
- get distributions to install them by default
- write man pages?
- add references to them where possible (from the nfsstat man
page, from howto's/faq's/?)
Steve promised me Red Hat would take care of this when these were
added to nfs-utils last year.
Until then, unfortunately, improvements to nfsstat are more useful,
since nfsstat is the thing people are more likely to run across.
Again, I think improving nfsstat at this point (which is merely for
compatibility with Solaris) would be wasted work, if we already have
what is needed in another tool. The Python tools are much more
sophisticated, and it would be confusing to add their functionality to
nfsstat (e.g. why can I zero the legacy stats with the -z option, but
not the stats the come from /proc/self/mountstats?).
Let's spend the effort on the tools that give us deeper results.
