While I certainly agree that cacti is a bit of a security nightmare,
what you suggest may not scale all that well for a site doing much
graphing. I'm sure the average cacti installation is recording
thousands of things every 5 minutes but virtually none of those are
ever actually graphed. Those that are viewed certainly aren't viewed
every 5 minutes. Even if polling and graphing took the same amount
of resources that would double the load on the machine. My guess
though is that graphing actually takes many times the resources of
polling. Just makes sense to only graph stuff when necessary.
