If I understand correctly, all these things (and Doug's reply too, where
he mentioned Cacti and Observium) rely on rrdtool under the hood and
rrdtool has a minimum interval of 1 second.  For this type of problem I
need to be collecting several values per second and keeping them for a
few hours, maybe a day at most.

I could probably script something myself using a time series database
backend but I was hoping there might already be some solution.
