When maximum values are selected in host heatmap report IC, average values are shown in the report instead.

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

How reproducible:

Steps to Reproduce:
1. Add a host to your engine
2. Stress the host CPU/Memory for a while
3. Open host heatmap report and select maximum values in IC
4. Compare real data with data in report

Actual results:
Average values in report

Expected results:
Maximum values in report

Comment 5 Shirly Radco 2015-11-11 08:24:21 EST

Can you please attach the actual cpu values for the hosts in your screensuts?
or send me a db dump if you are not sure how?

Thank you.

Hi, unfortunatelly I already don't have the engine nor hosts. But from what I remember I used stress for a minute or two each hour. The CPU/RAM usage was up to above 90%. This was shown correctly in report for max values. But report with average values was exactly the same even though the CPU was not used at all for the rest of time (~58 minutes).

Hi Karolína,

I checked the Heatmap reports and I don't see the issue you encountered.
I attached an example for running the report on the same hosts on the same time frame and I get different results for average and Maximum.

Please try checking this again and update the bug with a db dump.
