Hello All,
We are writing a new graph and would like some clarification on the
fields in this APC temperature graph that we are using as a template:
The report part makes sense for naming, etc.
The DEF part makes sense as it tells us what RRD1 counter to use (based
on the alias from datacollection-config.xml) and it looks like the DEF's
are also finding the min and max temeratures.
My question is in the CDEF.... ftemp makes sense as it is converting the
celcius to Farenheit (take the counter, X9, divide by 5, add 32), and
the same for the minFtemp and maxFtemp
The Line2 command I assume is drawing the line on the graph, as the
0000ff is thickness and color of the line? As well as the name of it.
Its the GPRINT I'm not getting. It calls ftemp for each of the average,
min and max....shouldn't it call the ftemp for the average (as defined
in the first cdef), but then the last 2 GPRINT entries also use ftemp
for min and max....shouldn't they use the minFtemp and maxFtemp that are
calculated in the 2nd and 3rd CDEF entries?
If so...how does this actually work? If not...why have the 2nd and 3rd
CDEF entries.?
I'm sure it's simple...but I be missing it.
All help is appreciated.
