This is a NOGO. cacti is an rrdtool frontend. And rrdtool does not provide real bar charts.

With suitably defined RRAs, you could use 'rrdtool xport' and draw graphs that way yourself. I don't think you could get Cacti to display them though, and it would mean you writing some graphics code.

I did this for myself, to get small last-3-hour stripgraphs on our intranet. These barcharts are the same sort of thing. It's not much fun to do though, and not an option if you aren't a programmer, or you must have the charts in Cacti's web interface.

I wasnt referring to the bars. But to the graph reinhard showed

To create the double-sided graph you have to create a custom CDEF something like CURRENT_DATA_SOURCE,-1,*

This takes the current data source, and multiplies it my -1, which inverts it. Only apply this new CDEF to the Line / Area graph item. When you add the min/avg/max items you will want to use the normal CDEF, otherwise you will get negative numbers printed.

Yep. Plus a CDEF

Code: Select all

cdef=CURRENT_DATA_SOURCE,1800,TREND

for the TREND (supported with rrdtool 1.2.x only).
