Description Yanping Zhang 2016-03-18 08:15:00 UTC 
Description of problem:
When quota/limits added on project ,create pod in project. On web console setting page, check the used percentage ratio and available percentage ratio of cpu and memory on the project quota metrics donut. The available percentage ratio is not accurate sometimes, so the sum of used percentage ratio and available percentage ratio  is not 100%.
Refer to attachment.

Version-Release number of selected component (if applicable):
openshift v1.1.4-16-gb5da002
kubernetes v1.2.0-origin-41-g91d3e75
etcd 2.2.5


How reproducible:
Always

Steps to Reproduce:
1.Make sure quota/limits added on project, create pod in project. eg:
# oc run testpod --image=openshift/hello-openshift --requests='cpu=15m,memory=50Mi'  -n prozyp
2.After pod is running ,check the used percentage ratio and available percentage ratio of cpu and memory on the project quota metrics donut
3.

Actual results:
2.The available percentage ratio is not accurate, and the sum of used percentage ratio and available percentage ratio  is not 100%

Expected results:
2.The percentage ratio should be right and the sum of used percentage ratio and available percentage ratio should be 100%

I don't see anything wrong in the screenshot. We're displaying percent used of total in the tooltip. We don't show the amount available anywhere.

15m used out of 1 core is 1.5% of the total. 1 core is the total.

Samuel:
  Sorry, I didn't  notice that another screenshot failed to be attached on. Pls check attachments again, The sum of available cpu ratio and the used cpu ratio is not 100%. Thanks!

Thanks, I understand now. Here is the fix:

Comment 6 Yanping Zhang 2016-03-23 07:52:19 UTC 
Tested on devenv-rhel7_3800:
openshift v1.1.4-198-g840e8fc
kubernetes v1.2.0-36-g4a3f9c5
etcd 2.2.5

When quota/limit are added on project, create a pod in project, check the used ratio and available ratio, they are precise and the sum is 100% now.

The bug has been fixed, so move it to Verified.
