You'll have to define one RemoteFPing probe instance per 'rhost'.
The probe executes just one command, something like 
'ssh rhost fping host1 host2 host3', so you can't have targets with
different rhosts probed by the same probe. This is exactly what a
'probe-specific variable' means in the documentation.

See the smokeping_examples document, particularly 'Example 3:
config.fping-instances', for an example of configuring probe

It's a bug in 2.0rc4 and RRDtool 1.2 compatibility. Thanks! Looks like
you're the first one to generate new RRD files with Smokeping.

There was another compatibility bug in RRDtools.pm reported today as
well, which shows up after one restart. We'll fix these for the next
