That reminds me of a blog entry from a year ago:
Just looking at zonestat.pl, it perpetrates many of the horrors I'm used to
seeing. That's not a criticism, just additional evidence that we desperately
need better interfaces to make getting some of this information easy. There
are - I think - 11 different binaries you invoke to get the various
bits of information
you need. While some of them could be replaced by inline calls to the Kstat
module, others clearly can't. Yet some of the information could just be stored
in kstats, which would make getting at it much easier.
I think what I'm saying is this: what can zonestat tell us about what additional
kstats should be kept, and what additional APIs would be useful to make writing
such utilities easier?
