Bug Description

When a node is disabled or down "nova hypervisor-stats" returns the total number of memory and vcpus even though that node is disabled or down.

It's not quite a bug, perhaps a wishlist entry but I would have expect the nova-hypervisor-stats to return the "usable" resources instead of the down/disabled/removed/present/active/etc resources.

The statistics is directly got from db: https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L671, and i didn't find models.ComputeNode has any fields to identify the hypervisor status as the bug report description, so the problem is how to identify the hypervisor status ?

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.

In case you want to work on that, consider writing a blueprints [1] and spec [2]. I'll recommend to read [3] if not yet done. The effort to implement the requested feature is then driven only by the blueprint (and spec).
