no, currently this information is not collected/regarded by collectd.
The data collected by collectd is always a *rate*, i. e. you'd end up
with information like ``status changes per second'' which, in 99.99% of
all samples, will be 0.0 – i. e. not very interesting.

It would be possible to have the `interface' plugin dispatch a
`notification' if a new interface becomes available or a previous
interface disappears.
