Thanks Jesse!
I can see individual ".rrd" files for numeric metrics, which are based on the
merric name. For example:
gmetric --name="Page_Hits" --value="9" --type=uint32 -> This will
generate a "Page_Hits.rrd" file
gmetric --name="Description" --value="Web Server" --type=string -> does
not create a "Description.rrd"
Both of these will showup on the gmetrics page, and the numeric one will
generate a graph, but only the numeric one seams to create it's own ".rrd" file.
Thanks,
Dave

I don't think that there is anything inherent in the .rrd files to distinguish
a "stock" metric (e.g. from gmond) from a "custom" one (e.g. sent via gmetric).
However, gmetad does keep track of the source of the data, and can provide
that. I think that this means if a metric hasn't been updated since gmetad was
started, gmetad won't know about it (I'm not 100% sure about that).
