Yes it can. rrdtool simply graphs the period you tell it to - if you tell it to graph a period covering one calendar month then it will do so. All you need to do is work out what start and end times you need for each month which isn't all that hard : start = "00:00 01-mm-yyyy" end = "00:00 01-MM-YYYY" - $interval where mm-yyyy is the month required, MM-YYYY is the result of adding one to the month and dealing with crossing a year end, and $interval is your graphing resolution. The results should be expressed as seconds since epoch. Actually, I'm not entirely sure if you need to subtract the interval. _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
