It depends what you want do do. I do a lot of simple maths using DRRAW in the CDEF field for each data source or by adding CDEF lines. Don't forget you can hide datasources by setting "-Nothing-" for the line/area type so you can just display the results not the original data. For some things where drraw can't quite cut it, I use rrdgraph outside of DRRAW (typically I use rrdcgi so I can easily publish to the web). See: http://oss.oetiker.ch/rrdtool/doc/rrdcgi.en.html I only bother exporting to .xml and import to Excel when I want to do really fancy scatter graphs and regression analysis. If you're going to want the performance data in a database all the time, you might consider changing your Nagios perfdata processing config to output the data to MySQL or whatever instead of or as well as to PNP.
