The max number is U (unknown -> not set) 100 is the number of seconds that may be inbetween updates. However, you are updating every 300 seconds. Result: each update is considered to be too old --> discard it. Try using 400 in stead. > The round robin archive keep 24 > samples of 5 minutes. yes > The factor does not mean anything, because my step > is 1, or not?. Well, technically you should say "steps" but yes, this is correct. (step is the default of 300 seconds per PDP. stepS is 1 PDP per CDP. step is for the entire database, steps is for each RRA) > To update de data base, I create a perl script (I´m not a Perl guru!) > wich run every 5 minutes that update like that: [...] > $comando = "c:\\rrdtool\\bin\\rrdtool update c:\\rrdtool\\file\\ras.rrd > N:".$number; > system($comando); 1: You can probably use $comando = "c:/rrdtool/bin/rrdtool update .... 2: You should be able to call rrdtool directly from perl > - rrdtool fetch ras.rrd AVERAGE > > 1032533100: -1.#IND000000e+000 [...] Yup.
