Unfortunately this didn't work as well as I hoped. I now have gaps in my
graphs, presumably because fping doesn't finish in time for all readings
to be gathered within one minute. I'm not sure that I can change "step"
and "pings" without corrupting my existing data. Can anyone help to
resolve this problem?

Also, can anyone advise me about the cause of the "fake smoke" in the
data that I posted previously?

Cheers, Chris.
