You are asking for the defaults of "now-1d" to "now" which is
86400/30=2880 rows.

There aren't that many entries in the database.  All but ten will
be "filled" (not really) with unknowns.

Verify this with either "rrdtool info" or "rrdtool dump".

??? It works for me.  What version are you using?  And how?  Please
modify your rrdtool create command so that it includes the start time
and retry / repost.
