Srikanth Sundarrajan commented on FALCON-796:
---------------------------------------------
Makes sense. I had considered and dropped it, as the triage options exclusively
reports only failed/unavailable sections of the dependency tree, if
operationally it would help, we can include it. Besides, it will also help the
falcon server by not overwhelming it with too much to do in a single call.

> 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

> {noformat}
> *falcon instance -type feed -name FEED-abc -start 2014-09-01T00:00Z -end
