Anyone thats seen MRTG (simple, static) on a large network realizes that decoupling the graphing from the polling is necessary. The disk i/o is brutal. Cacti has a slick interface, but also doesn't scale all that well for large networks. I prefer RTG, though I haven't seen a nice interface for it, yet.

If you're pulling data from a database, pull it all and generate static HTML files. Then you don't even need CGI functionality on the end-user interface. It thus scales much better than the dynamic stuff, or SSL-encrypted sessions, because it isn't doing any computation.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.Chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iD8DBQFFtE/NElUlCLUT2d0RAtbeAJ91qMtm8VtWSLHJ/gLsg3DnqitlwQCeK1pn bqmZZoK821K76KMj/0bxDNk= =Rx6P -----END PGP SIGNATURE-----
