Hi, I've been building some stats of our wifi usage. The rrds were all created using DS:GAUGE and RRA:LAST. The problem is that I see some discrepancies between the graph that shows all accesses since the beginning of the logging and the graphs that refer only to a given interval (either a month, a trimester, etc). You can see that for yourselves here (each row represents a kind of statistic and each column represents a different sample interval):
http://www.core.ipp.pt/stats/rrd/isep.ipp.pt/images/ Looking at those images, it seems clear to me that there's a big difference in the graphs generated for the month of April, for instance, and the part referring to April in the first graph. Remember that in each row, the rrd is the same.. The only difference is the interval. Is this normal? Is there some interpolation (or something similar) happening here?
