[Bug 1446716] [NEW] Scheduler weighers do not output individual weights to debug log

 

Public bug reported:

In the nova scheduler (and nova-cells) the filters report debug level
logging on what decisions each filter makes on the hosts(cells). The
weighers, however, only give the combined weight after all have been
applied. As an operator, I want to be able to see the weight each
weigher contributes in the debug log so that I can troubleshoot
scheduler problems better.

** Affects: nova
     Importance: Undecided
         Status: New
