Description ldomb 2016-08-16 20:54:20 UTC 
Description of problem:
When creating a report for container chargeback with the following values 

Memory Used
Memory Used Cost  

the memory total for example for openshift-infra shows 184.4 GB. 

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


5.6.0.13.20160624114606_13a9153


How reproducible:


Steps to Reproduce:
1. Create a report with the values 
Memory Used
Memory Used Cost 

Actual results:
Memory values do not seem to be based on container usage. 

Expected results:
Correct value for memory consumption

Laurent the memory reported (184.4 GB) is based on the summation of all the pods in the project per each hour.

So for example if the relevant project has multiple pods that are using 7 Gb of memory (total) for 24 hour, then the we would be charging the use of (7 * 24) 184 Gb.

Anyway I'll leave you to investigate this further with Ari.
Comment 4 Ari Zellner 2016-08-23 14:16:04 UTC 
180 GB is plausible.
Possible scenario: openshift-infra had 3 pods running for 24 hours 
Each pod uses 2.5GB of memory an hour.

The chargeback report for that day would show 24 * 3 * 2.5GB = 180gb in mem used.

Can I move this to POST?

Yes please move post. Thanks for the explanation.
