Viewing the current and previous day together in one Graph

Post by Clemens »

Hi all,

I'm new to cacti, so I have to apologize in advance if this is a FAQ
but I can't find a solution in the forum.

I'm collecting some GAUGE data which represents throghputs for
a messaging system (and maybe other purposes in ther future).

Up to now we did the graphs with gnuplot and for fast and easy
comparision we put the up to date data together with the last day
data in one graph.

Derived from the RRDtool man pages I know that there exist similiar
functions for RRDtool Graphs too.

Using DEF option with an extra parameter
e.g.: DEF:lastday=test.rrd:ds0:AVERAGE:end=now-1d:start=end-1d
or using the SHIFT option
e.g.: SHIFT:lastday:86400

Is there a possibilty to use this options in cacti?
If so, how can I configure those.

Thanks
Clemens
