Hello, I have a problem with win32 rrdtool (1.3.8 pre compiled version), I am rrdtool beginner and used it only once for multiple temperature sensors draw so I am not experienced enought to fully understand fully how this powerfull RRDTool work.
Today I want to use RDDTool again to graph HEC / CRC error's counter of DSL router, so I create a one minute step .rrd with enought rows to get more than a year of data. rrdtool create hec.rrd --start "1257698388" --step 60 DS:HEC:GAUGE:600:U:U RRA:AVERAGE:0:1:600000 1257698388 = 08 nov 2009 16:39:48 But if I ask for rrdtool first and last I get weird values : first = 1221698400 = 18/09/2008 00:40:00 <= 2008 ??? last = 1257698388 = 08/11/2009 16:39:48 I don't understand first and last date, why 2008 , why last is --start value ? Now I add a few entries rrdtool update hec.rrd 1257698...@41907 1257698...@41907 1257698...@41907 1257698...@41907 1257698...@41907 1257698...@41907 1257698606 = 08/11/2009 16:43:26 1257698821 = 08/11/2009 16:47:01 1257698908 = 08/11/2009 16:48:28 1257698933 = 08/11/2009 16:48:53 1257698956 = 08/11/2009 16:49:16 1257698965 = 08/11/2009 16:49:25 And ask first/last again first = 1221699000 = 18/09/2008 00:50:00 <= 10 minutes diff from previous request ??? last = 1257698965 = 08/11/2009 16:49:25 OK this is real time of last entry Why first value differ from previous request ? regards. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
