Graph the value difference per interval

[Devroush]

Hi,

Sorry for the (probably) unclear title, but I couldn't come up with anything better. I've made a script that reads in some values, 4 to be precise. For 2 of them, I want to use a GAUGE. However for the other 2, I want to graph the difference for each interval. For example in the 5-minute graph, I want to see the difference between time A en time A + 5min. If at 10pm the value is 1000 and at 10:05pm 1010, then I want to show just 10 on the 5-minute graph.
However for the yearly graph (with 1 day average), I want to show the difference for each day.
I hope my question is clear enough? Is this even possible?

Thanks in advance.

Use the CDEF called 'make per 5 minutes', which should do this for you. You'll find it in your graph templates.

However for the yearly graph (with 1 day average), I want to show the difference for each day.

I recommend you read through the documentation site and/or the rrdtool site on how rrdtool consolidates your data. You can increase the history so rrdtool doesn't consolidate your data for a whole year, but the files are going to be giant.
