[Bug 1407939] Re: _poll_volume_usage and _heal_instance_info_cache should allow default 0 value

 

This wishlist bug has been open a year without any activity. I'm going
to move it to "Opinion / Wishlist", which is an easily-obtainable queue
of older requests that have come on. If you decide to work on this
consider using a blueprint [1] (maybe with a spec [2]). I'll recommend to 
read [3] if not yet done. 

NOTE: 
We are currently working on improving the help text of all config options (bp "centralize-config-options-newton") and these options will also get a proper help text then.

Title:
  _poll_volume_usage and _heal_instance_info_cache should allow default
  0 value

Status in OpenStack Compute (nova):
  Opinion

Bug description:
  currently timely function _poll_volume_usage and _heal_instance_info_cache 
  don't allow CONF.volume_usage_poll_interval, CONF.heal_instance_info_cache_interval to be 0
  respectively ,otherwise the function will not be executed 

  oslo already checked _periodic_spacing if it's < 0, then the periodic task is disabled
  it's = 0, then the periodic task spacing is default (60) so no need to check it in nova manager
