Description Meiyan Zheng 2020-06-15 08:00:35 UTC

Description of problem:

When checking Hypervisor status with Admin --> Compute --> Hypervisors in dashboard, pCPU usage information is not included when configured cpu_dedicated_set in nova.conf, such as:  

[compute]
cpu_shared_set = 0,1,4,5
cpu_dedicated_set = 2,3,6,7

https://specs.openstack.org/openstack/nova-specs/specs/train/implemented/cpu-resources.html


Version-Release number of selected component (if applicable):
- RHOSP16 

How reproducible:

Steps to Reproduce:
1. Configure vCPU and pCPU settings in nova.conf:
[compute]
cpu_shared_set = 0,1,4,5
cpu_dedicated_set = 2,3,6,7

2. Create instances on above compute node 

3. Check Hypervisors status in dashboard with Admin --> Compute --> Hypervisors

Actual results:
Only show total vCPU numbers

Expected results:
pCPU usage also should be included

Comment 7 Artom Lifshitz 2021-11-01 13:44:00 UTC

From the Compute point of view information about vCPUs and pCPUs is consumable via the Placement API, and is accessible on the command line with the `openstack resource provider` series of commands, as Francois pointed out in comment #5.

We've made a point of removing usage information from the `hypervisors` API [1] as it was "frequently misleading or outright wrong [and] can be better queried from placement" - and do not intend to re-add anything back to it.

It is up to the Horizon team if and how they want to present the information from the Placement resource providers APIs in the UI.

Hi Team,

Good day.
So may understand that the fix would be included in RHOSP 18.0 ?

Regards
Sam

Sadly, it's not a fix, it's a feature that requires new code.

We have it initially planned for osp18, but as you can see, it hasn't been ack-ed by PM yet, so it may still change.
