>             Project: Nutch
>          Issue Type: Improvement
>          Components: generator
>    Affects Versions: 1.15
>            Reporter: Sebastian Nagel
>            Assignee: Sebastian Nagel
>            Priority: Minor
>             Fix For: 1.16

>
> During the map phase of the selection step, the generator rejects many 
> (usually most of) items for various reasons:
> - not yet time for a refetch (returned by the fetch scheduler)
> - generator score too low
> - status does not match restrict status
> - Jexl expression not matched
> and some more. It would be useful if the reasons are counted and logged, esp. 
> when the CrawlDb gets bigger and multiple options to restrict the selection 
> are used.
