Your DEF points to a DS of "util", but you apparently have DSs of
"edge01" and "edge02", so you'll need another DEF, another LINE#, and
(optionally) more GPRINTs. That's assuming you want two on one graph.

Will every host that has "fmsconns" have a status with exactly two
edge* values? Or with exactly four edge* values? I find that unlikely,
given the two digit numbering, and (also to some extent) the
discrepancy between the status message and the NCV_fmsconns line. If
the count of values can differ (e.g. you might eventually have a host
with 1 or 3 or 5 or 6 values) then SPLITNCV might be the way to go,
but that has its own complications (e.g. multigraphs). Changing the
number of DSs in an RRD is not easy.
