Hmm, I thought I was one of the few that understood this.
In this case someone wants to update his archive with one value per day. Why would you want to have 24 intervals per day? If he sets his step to 86400 and his ds heartbeat to: 86400 + (a small interval in case he runs late with his daily update) And he does his first update at midnight, wouldn't that just be what he wants? His pdp's would be at 00:00 exactly. I can see why your method works, but wonder what the advantage is. b.t.w., on the rrdtool site under the heartbeat and the step it says: ``heartbeat'' is not only the maximum acceptable interval between samples, but also the maximum acceptable amount of ``unknown'' time per PDP (obviously this is only significant if you have ``heartbeat'' less than ``step''). Is this right? I believe that the x-files factor for the ds is the parameter that determines this.

With a step size of 86400, the interval will begin and end at n*86400. This means, for Europe, 02:00 local time to 02:00 local time. In the USA it will be something around 18:00 to 18:00, in Australia it will be 11:00 to 11:00 et cetera. With a step size of 3600 and updates at 00:00 local time, 24 intervals will be set with just one update, provided that heartbeat allows it. All of the intervals between the last update (00:00 yesterday) and the current one (00:00 today) will be set to the same rate. cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
