Hi Rafal, /"choose the aggregation function that makes most sense in your case, for example the average."/ That's the problem: If I calculate and store 10-minute values, which function is for an hour / day good? For a small factor between 'store' interval and rrdgraph intervall MIN / MAX can be approximated used.
So my idea is to calculate & store for 99% and 5% percentil the data in RRA for some intervals i.e. 15/30/60 min, 3/6/12/24 hours. And hope, rrdgraph choose the best fitting RRA. But how can I bring the data in a rrd file? rrdupdate is not possible. Possible every 15 minute: rrddump > add the required values in the xml file > rrdrestore. But then the RRA are growing infinitely? Or better: 2 x 7 RRD files with only one RRA. This can updated with CF LAST. But then I have a problem with Cacti. Which File is the Datasource? So dump all 7 RRD to xml, Merge it together to an format with all RRA, and restore this RRD to show it in Cacti.
