to remark a graph

[Sem]

I monitor a port on HP switch. A port name is just a module name and a port name combination - like A12, B8. Not informative really.

I'd like to add a note for a graph but I see no ways to do it.

I've tried to change a graph title. But after I change it, graph losts its data source and it's not displaied anymore.

Here is a debug output for the graph:
-----------------------
RRDTool Command:

/usr/local/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="hp5308-1-er5 - Traffic - F1 - test" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bits per second" \
CDEF:cdefa=a,8,* \
AREA:cdefa#00CF00:"Inbound" \
GPRINT:cdefa:LAST:"Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total In: 0 bytes\n" \
LINE1:cdefa#002A97:"Outbound" \
GPRINT:cdefa:LAST:"Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total Out: 0 bytes"

RRDTool Says:

ERROR: invalid rpn expression 'a,8,*'
---------------------

As you can see DEF fields lost after I've edited the graph title.
They was something like that:

DEF:a="/usr/local/share/cacti/rra/hp53081er5_traffic_in_351.rrd":traffic_in:AVERAGE \

Any comments?

Double check that you have data sources associated with that template correctly.
