Print on same graph current data and data of 24 horas before

[cfrodri]

Hi,

First of all, I have to say I haven't got any experience working with Cacti. I want to print in the same graph current traffic of a interface (it's already working fine!!) and the traffic of same interface 24 hours before. So it should be very easy to compare both lines (current and yestarday traffic).

Anyone can help me?

Thx a lot,
Carlos.

Pricipally, this is possible using latest rrdtool from cli (see: http://www.vandenbogaerdt.nl). But this has not yet been implemented. You may use my "TimeShifter" as an alternative. Currently, it is published as a patch (search the forums). AFAIK, latest SVN has incorporated this function, so it will be there with next release if you do not want to use SVN code.
