Hello Russell...
Thank you for your responses =)
I believe I am pointing to the correct rrd. In fact, I have tried a
dozen or so rrds which I know for a fact are active and being used to
generate graphs in the Smokeping Web UI.
From the Web UI this is the URL which gives me a graph with current
stats, not a time period of un-reachability (nan).
