I did/do indeed. I'm likely to build a two-tier setup: * A SQL based long-term storage solution with raw data. * A (most likely) rrd based "frontend" storage solution which would allow easy graphing as well (which I currently use gnuplot for). I might need to get some SSD disks to be able to import the raw data into rrd files in a relatively fast way. Using rrdtool as single backend isn't an option. With the ammount of details we want to keep over time, the rrd files would be quite large. And since each rrd update pretty much requires the complete file to be "rewritten", the performance would be pretty bad. -- Regards, Ruben Laban Senior Systems and Network Administrator ISM eCompany _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
