The RRDTool PDP (primary data points) are formed after Normalisation. The Normalisation process adjusts the data back in time to a Step boundary -- IE, if step is 's' and time is 't', then ( t mod s ) = 0
So, whatever time you submit your sample at, if your step is 5 then the PDP time will be a multiple of 5 (seconds since the Epoch). Understanding Data Normalisation is a bit more of a job and I can recommend this tutorial - http://www.vandenbogaerdt.nl/rrdtool/process.php Steve Steve Shipway University of Auckland ITS UNIX Systems Design Lead [email protected] Ph: +64 9 373 7599 ext 86487 _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
