Traffic usage report?

[luke240778]

I am wondering if there is some kind of traffic usage report or something so i can see how many users are on at any give time?

For example, i have a WiSP, slowly getting bigger.. to help with bandwidth costs at the start, i need to be able to see for example how many out of say 50 users are actually online at any give time.  Hopefully so i can see like there is never anymore than say 40 users actively using the internet at the same time.. so i then know that only 80% are on at the same time..

Any ideas?

I dont think there is a package that will do everything that you want but what I use is darkstat and bandwidthd.
Darkstat description:
darkstat is a network statistics gatherer. It's a packet sniffer that runs as a background process on a cable/DSL router, gathers all sorts of statistics about network usage, and serves them over HTTP.
This will tell you when it last saw a certain IP.
bandwidthD description:
BandwidthD tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization. Charts are built by individual IPs, and by default display utilization over 2 day, 8 day, 40 day, and 400 day periods. Furthermore, each ip address's utilization can be logged out at intervals of 3.3 minutes, 10 minutes, 1 hour or 12 hours in cdf format, or to a backend database server. HTTP, TCP, UDP, ICMP, VPN, and P2P traffic are color coded.
It will tell you the users that are on daily, and how much data they are using.

Hope this helps.
