MRTG and other things will do this kind of alerting for you if I am not mistaken. Certainly programs like Nagios and other "network" monitors can/will. You will find that the more customers on a link (that is, the more the link resembles a backbone link and not a customer link) the less spikey the traffic is in general. Individual/end-user links may need "upgrade" far sooner than their avg or 95th suggests. (Depending on QoS needs). The smaller the circuit, the more so. (Small here is anything under a Gigabit/s).

Greetings,
I'm working on a system to alert when a bandwidth augmentation is needed. I've looked at using both true averages and 95th percentile calculations. I'm wondering what everyone else uses for this purpose?
We're talking about anything from a T1 to an OC-12 here. My guess is that the calculation needs to be slightly different based on the transport, but I'm not 100% sure.
Thanks,
