Just to make sure I understand you: With "octet string" you mean
"A:\" and "/export/home" and such?

Typically these would be set from the calling script, not from
within RRDtool itself.  RRDtool doesn't even have knowledge on
this; RRDtool just stores numberic values.

Your script should take care of proper quoting of the string; colons
and backslashes have special meaning. Then it's just a matter of
setting a variable (outside RRDtool) and using that variable in your
graph script; it is substituted before RRDtool gets to see it.
