Hi Everyone , good day

we have openstack environment in our office, I am new to openstack and I need assistance for the below

we have 1 controller node + 1 Block node + 10 hypervisors added in our environment. (Ubuntu 16.04 + openstack) . we have separate projects and

One of the developer is not able to create new instances , getting this error (then someone said openstack is running out of resources , if I saw the Admin view overview- it has 1/3 utilization in RAM, VCPU is little full , 1/3 utilization in Disk- not sure how it is full)

openstack --os-project-id=0ba8f04fe5a145e5a9820454c991b2c9 --os-user-domain-name=Default --os-auth-url=http://OPENSTACKAPI:5000/v3/ --os-identity-api-version=3 --os-username=test --os-password=TEST server list The request you have made requires authentication. (HTTP 401) (Request-ID: req-ffcab1d8-84cb-4b39-89b6-b1c2d272d906)

So my manager requested me to make a report on open stack utilization.

Can some one please assist me how to get this done 1. How to find the non-utilized instances(not running from the past 30 days ...etc) 2. Do we have any tools to get the utilization metrics in open stack. 3.
