F5 BigIP Virtual Server Query

[LoOoD]

Has anyone got this working? I'm haivng trouble setting it.
I'm using cacti 0.8.6h. bigips are running 4.6.4.

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="bigip1 - VS Traffic (bits/sec)" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bits per second" \
--slope-mode \
CDEF:cdefa=a,8,* \
CDEF:cdeff=a,8,* \
AREA:cdefa#00CF00:"Inbound" \
GPRINT:cdefa:LAST:" Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s\n" \
LINE1:cdefa#00694A:"Inbound (Peak)\:" \
GPRINT:cdefa:MAX:" %8.2lf %s\n" \
LINE1:cdeff#EAAF00:"Outbound" \
GPRINT:cdeff:LAST:"Current\:%8.2lf %s" \
GPRINT:cdeff:AVERAGE:"Average\:%8.2lf %s\n" \
LINE1:cdeff#FF0000:"Outbound (Peak)\:" \
GPRINT:cdeff:MAX:"%8.2lf %s"

RRDTool Says:

ERROR: invalid rpn expression in: a,8,*

Also what should I set the "Index Value" for the VS Traffic data source?

Any updates to this? The attached files don't seem to match any interfaces on newer F5's.
