The Source Monitor status colors are defined as follows:
Green: Successfully harvested ("success")
Blue: In progress ("in_progress")
or has partially harvested, "success_iteration" - means that the most recent harvest cycle completed but not all available documents were harvested because of document/cycle limitations.
Red: Harvested with errors ("error")
Yellow: Not yet seen by a harvester, or currently unapproved.
Suspended sources retain their color status but have "[SUSPENDED]" prepended to their title.
If the colored "Status" column contains numbers, eg "0/20" then it is referring to the (beta) distributed source function - the left number is the number of "in progress" threads, and the right number is the total number of threads.
