> Falcon has a wealth of information that can help users to triage issues
> relating to their pipelines, but this information is not available in a
> consumable form to the users. Here is a suggestion to solve for this issue to
> some extent.
> In a typical usage scenario, users may find that their data has not been
> generated and that would require them to walk up the dependency tree to
> identify the root cause. Luckily all this information is available within
> Falcon and can be surfaced.
> A mock of how this would look:
> *falcon instance -type feed -name FEED-abc -start 2014-10-01T00:00Z -end
> 2014-10-01T00:00Z -triage*
> {noformat}
> FEED-abc/2014-10-01T00:00Z MISSING
> + PROCESS-def/2014-10-02T04:00Z WAITING
> + FEED-ghi/2014-10-01T00:00Z MISSING
> + PROCESS-mno/2014-10-01T01:30Z RUNNING
> + FEED-ghi/2014-10-01T01:00Z MISSING
> + PROCESS-mno/2014-10-01T02:30Z FAILED
> + FEED-ghi/* AVAIALBLE
> + FEED-jkl/* AVAILABLE
> {noformat}
> *falcon instance -type feed -name FEED-abc -start 2014-09-01T00:00Z -end
