Monitoring bandwidth per host, how to graph?

[sethbest]

Hello,
I have Cacti setup, and working in an office of ~100 systems. My goal is to monitor bandwidth spikes on each system, but I'm missing an effective way to output that data (short of just clicking on each device one by one). I added each PC as a device, and can graph the network adapter fine. I'm not sure where to go from there.
I would like some way of seeing 1. when there are overall increases in bandwidth usage, and 2. which devices are the worst offenders.
Thanks for the help.

Is it safe to assume due to the lack of responses that this is unfeasible? I suppose 150~ lines on a line graph would be a bit cluttered. Does anyone have any tips of other ways to go about this type of bandwidth monitoring?

I haven't used it in a good while, but you may check out the ReportIt plugin.

Honestly, what you are attempting to do isn't something that Cacti really does. You are probably needing a custom plugin that works somewhere between thold and reportit.

I assume you are trying to monitor bandwidth as it relates to a single shared uplink (to a server or the internet or something) and not just the combined "any to any" sum of all possible traffic to all possible hosts, right? If so, why not just use Netflow data from the switch or router?
