Hi, I have an another (last) question.
When i use a xff of 0.8 for the frequency 5 minutes, the rrdtool does not calculate correctly the average if the there is only one value. For example, if i have the values : 4 Nan Nan Nan Nan The stored value for 5 minutes is 4 (4/1) instead of 4/5. Is it normal and is there a solution ? Sam had talk about a solution to "collect and batch several RRD updates to run at once" but i do not find the information in the archive list. Could you indicate me the method.
