sflow -> aggregated aspath visualization?

[athompson at merlin.mb.ca (Adam Thompson)]

Iâ??m looking for product recommendations:

Weâ??ve noticed that about 20% of our traffic here lately has decamped from the free (or, at least, flat-rate) connection to CANARIE (our R&E network) and its various connected content-delivery networks, and onto our commercial provider.
While this is presumptively a legitimate shift, weâ??d like to better understand these changes when they occur, in a way that our executive can understand at a glance.
We do have sFlow (et al.) going to an Arbor PeakFlow box for analysis, but itâ??s lacklustre at best at understanding changes like this.
I want:

  *   Top #n ASNs by traffic volume, per router/interface, stacked chart
  *   Some way to visualize large jumps in that dataset, e.g. if Cloudflare ditched their CANARIE connection and now that traffic all goes commercial, I donâ??t know what sort of graphic would be useful, maybe a stacked polar chart so you could see when an AS jumped from one sector to another?  Even stacked bar charts could be useful.

If anyone knows of tools capable of generating easy-to-understand reports, dashboards, including historical â??what changed this weekâ??-type data, please let me know.

For that matter, if you have a technique of collecting this data and using Excel to do the reporting, that would work too.

(Yes, I could theoretically build this off of existing open source toolsâ?¦ eventually)

Thanks,
-Adam
