I see. This will probably take a lot of experimenting on my part to figure this out then. Do you have an idea what kind of drive space might be involved for a year's worth of 5 minute polling (daily) for, say, basic network I/O? Something I do now is archive my daily/weekly/monthly images at the appropriate times respectively as well as the basic HTML surrounding the relevant image. http://neo.pittstate.edu/stats/network/archive/daily/020806/kr-pittsburg-io.shtml I was giving this some thought as I pondered switching to RRD tool for the data logging side of things. I was thinking about writing a script to have rrdtool create me an image for archiving at the intervals I need. For the 2001 year, that archive with a total of around 50 targets using PNGs. If I could save some of that space and just have RRD store the raw data for an extended period of time, I think I could save a fair amount of resources (drive space, CPU time to create images, CPU time AND drive space to archive images). Would this be a good way to go about this? I need to just jump into RRD sometime like I did with MRTG at one point.
