I am trying to add a custom RRD-Graph showing data collected on an
300s intervall in an per hour graph. The rrdgraph docs mention the
option --step (-S).
Unfortunately I haven't found any way to add this option to a
certain graph-definition.
After taking the Graph commands (exluding -F -E etc. / beginning
with the CDEF Statements) and adding them the customgraph definition
(and removing the datapoint/line definitions from the gui):
--step 3600
CDEF ...
DEF ...
I get an empty-graph.
The step option is only used during the creation of the RRD file and
is not a graphing option. The time period shown by the graph is
controlled by the zoom controls and the range selection at the top of
any perf tab. If you want to add an "Hour" range you can do so in
zendmd like so..
dmd.performanceDateRanges.insert(0, ('One Hour', 3600))
