Well, based on my research through thwack and solarwinds, you can't do it. I found an entry from NPM 9.x that said flat-out, you could not transform more than the last value, i.e. transforms only work on the current value of the poller you are transforming. So, the answer is to transform it, tell the transform to save the history, then chart that history and that is as close as I can get. I have not found were I can pull the last "x" # of entries from the transform history or a regular poller. The charts in NPM are doing it everytime they update, but I do not see a way to do it short of performing a direct SQL query on the Orion database. Can anyone tell me if I have to go down that road or if there is a more pragmatic way of doing it?
