sflow -> aggregated aspath visualization?

[Adam Thompson <athompson () merlin mb ca>]

I’m looking for product recommendations:

We’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, we’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 it’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 don’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 “what 
changed this week”-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 tools… eventually)

Thanks,
-Adam
