    Description

      An overview about fetch times and fetch intervals could be useful to configure a crawl. CrawlDbReader could easily calculate min, max and average and show it as part of the statistics job (command-line option -stats):

      % bin/nutch readdb .../crawldb/ -stats
      ...
      TOTAL urls:     544910
      shortest fetch interval:       7 days, 00:00:00
      avg fetch interval:            7 days, 17:43:58
      longest fetch interval:       10 days, 12:00:00
      earliest fetch time:   Wed May 25 11:42:00 CEST 2016
      avg of fetch times:    Sun Jun 05 18:11:00 CEST 2016
      latest fetch time:     Wed Jun 22 10:25:00 CEST 2016
      ...
