No. Step tells the spacing of the original data points. This is critical and not related to RRAs. Combined with the start, it specifies the timestamps for all future updates. If you don't update at exactly those timestamps (start+step, start+2*step, ...) rrdtool will interpolate to figure out what the value would have been at the correct time-stamp. For many things this doesn't matter greatly. If you want precise data, this is important. >Jeff >----- Original Message ----- >From: "Thomas Erskine" <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]>; <[email protected]> >Sent: Thursday, May 08, 2003 04:01 >Subject: [rrd-users] Re: Step vs. Heartbeat > > >> At 04:34 2003-05-08, [EMAIL PROTECTED] wrote: >> >Can someone explain to me what the difference between step and heartbeat >is? >> >> Step specifies the resolution of the data (e.g. one point every 5 >> minutes).
