you keep answering this issue with a standard response... you can't do it technically. when will your code be able to 'technically' maintain the maximums and not the averages in the historic graphs.. almost ALL of our needs are to find out what the peaks were. we don't really give a rip what the averages are.. they are totally useless to us.
even for traffic monitors over time.. we don't need to see how it averages out (and down) over time looking at month, year, etc. We want to compare today's real values to historic values that also show the peaks.
Right, so we have to pull historic graphs to get the numbers we need.
Poll your customers and I think you would find that this is something useful, and the fact that the historic graphs erode and don't really reflect what has happened.
Please please please consider this alternatives for keeping history. carry forward the peak number rather than averaging a range. that can't be technically impossible to do.
