This seems to be the most common faq on the rrd mailing list ! RRD stores rates (<somethings> per second). It does not store accumulated totals or anything else, only rates. To get the cumulative total over a period, take the rate and multiply by time - and make sure you use the average consolidation function in the rrd. Eg, if you graph showed an average of 1kbyte/s over 24 hours, that would work out to 86400 kB total (1kBps time 86400 seconds/24hr). The RRD tool pages are at http://oss.oetiker.ch/rrdtool/ I'll see if I can find time to extract some of the less embarassing bits of my script for generating graphs and post them :-) ------------------------------------------------------------------------- Take Surveys.
