> Scraper synthesizes a view of routing protocol link state costs from multiple log files. This view identifies a stable state when all routers are reachable and when all routers agree on link state costs.
> Identifying when link costs are in flux may help identify periods of instability and be the root cause of unexpected message dispositions.
> DISPATCH-1183 exposes some of the inner workings of the link state cost calculation on a ring of 26 routers.
> The proposal for this issue is to highlight the time-of-day fields for AMQP sent or received when the costs are unstable.
