Show Hypervisor Statistics (DEPRECATED)
=======================================
.. rest_method:: GET /os-hypervisors/statistics
max_version: 2.87
Shows summary statistics for all enabled hypervisors over all compute nodes.
.. warning::
This API is deprecated and will fail with HTTP 404 starting with microversion
2.88. Use placement to get information on resource usage across hypervisors.
Policy defaults enable only users with the administrative role to perform
this operation. Cloud providers can change these permissions through
the ``policy.json`` file.
.. note::
As noted, some of the parameters in the response representing totals do not
take allocation ratios into account. This can result in a disparity between
the totals and the usages. A more accurate representation of state can be
obtained using `placement`__.
