And it is right.  There is a difference between the CF "LAST" and the
function used in (G)PRINT.  MRTG generated RRD files don't contain RRAs
other than MAX and AVERAGE.  If you need MIN and/or LAST, you need to
create the database yourself.

To print the last seen value (using GPRINT) you don't need a special CF.
