</div>I don't understand with "SPLITNCV applies the same graph type to each<br>
dataset".<br>
<br>
With SPLITNCV you have multiple rrd files, each of these hold one data<br>
item and you define in the SPLITNCV setting what RRD datatype they are -<br>
essentialy GAUGE or COUNTER. E.g. SPLITNCV_foo="ds1:COUNTER,ds2:GAUGE"<br>
<br>
In the graph definition, you just refer to the specific RRD-file you want<br>
to pull data from. This has no relation to the data being a GAUGE or a<br>
COUNTER. So the graphs.cfg definition is straight-forward:<br>
<br>
[foo]<br>
DEF:foo1=foo,ds1.rrd:lambda:AVERAGE<br>
DEF:foo2=foo,ds2.rrd:lambda:AVERAGE<br>
AREA:foo1#FF0000:foo 1 data<br>
STACK:foo2#0000FF:foo 2 data<br>
<br>
<br>
