I think this is the most practical option.  But I think this also
requires root privileges.  Perhaps sudo could be used to restrict this a
bit.

I think the important question is what to actually trace or what
statistics to compute.  Dtrace is very flexible, but perhaps it's more
useful to help understand complicated situations than to build
monitoring tools.
