I have, and it doesn't work, get errors complaining about
ERROR: No <ds> tag found
It's apparently not enough to create additional elements,
which look like what I have below. Oh well, time to hit
the rrdtool mailing lists...
<ds>
<name> ds0 </name>
<type> GAUGE </type>
<minimal_heartbeat> 1800 </minimal_heartbeat>
<min> NaN </min>
<max> NaN </max>
