	incoherent fetch and graph on year scale by Sebastien MICHEL-3 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message hey, I would like to know if my problem is an rrdtool bug or a usage problem. I am on unstable debian and use : RRDtool 1.3.8 Copyright 1997-2009 by Tobias Oetiker <tobi@...> Compiled Jun 2 2009 18:23:37 works : rrdtool fetch data/temp-LFBO.rrd --start "-31d" --end now AVERAGE doesn't works: rrdtool fetch data/temp-LFBO.rrd --start "-32d" --end now AVERAGE rrdtool fetch data/temp-LFBO.rrd --start "-1y" --end now AVERAGE the "rrdtool fetch data/temp-LFBO.rrd --start "-32d" --end now AVERAGE" result is a part of the first sample of "rrdtool dump data/temp-LFBO.rrd" strange isn't it ? You can get the database here: http://meteo.falguerolles.org/data/temp-LFBO.rrd To create my db: rrdtool create temp-LFBO.rrd --start $(date +"%s") \ --step $TEMPS \ DS:temp:GAUGE:$((TEMPS * 2)):U:U \ RRA:AVERAGE:0.2:1:$TEMPS \ RRA:AVERAGE:0.2:6:168 \ RRA:AVERAGE:0.5:12:372 \ RRA:AVERAGE:0.8:144:36500 # "RRA:AVERAGE:0.2:6:168", # moy sur une heure pour tout une semaine => 6data * 10min = 1h : 24h * 7j = 168 # "RRA:AVERAGE:0.5:12:372", # moy sur 2heures pour tout un mois => 12data * 10min = 2h : 372 = 12 * 31 valeur = 12 valeurs par jour # "RRA:AVERAGE:0.8:144:365" # moy sur un jour pour un ans => 24h * 6data =144data pour une journee : 365jours (valeurs) par ans * 100 years. thanks, regards, -- Sébastien If you don't understand how to do this, then read the documentation. If you still don't understand this, then go fetch a guru to help. If the guru doesn't understand, get a new guru... _______________________________________________ rrd-users mailing list rrd-users@... https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
