57102's Appliance CPU usage screenshot
FYI, for a 5.7.1.0.2 appliance to be compared with the results above, I'm attaching the screenshots for: 1. avg of User CPU values on a default idling appliance with 4 vcpus, over 30 minutes. In latest version, this appears to be much higher than what we see in 5.5x / 5.6x. 2. similarly calculated average of MIQServer User's CPU value, which is almost equivalent to its 5.6x mate, but higher than 5.5x, as per the screenshots in #c0 Attachments: - https://bugzilla.redhat.com/attachment.cgi?id=1255865 - https://bugzilla.redhat.com/attachment.cgi?id=1255866 This bug has been open for more than a year and is assigned to an older release of CloudForms.

Created attachment 1164229 [details] Appliance CPU Usage + Per Process Miq Server CPU Usage Description of problem: I am noticing a bit more than normal cpu usage occurring when appliances are idling on infrastructure with 5.6 appliances vs 5.5 appliances. Digging through per process metrics the additional cpu usage appears to be originating from MIQ Server (5.6) when compared to evm_server.rb(5.5) When viewing all vcpus usage summed together (0-400% on 4vcpu default appliance) I am seeing an average of 5% more cpu usage. This appears to be attributed to the Miq Server process when compared to evm_server.rb. See attached graphs for details, Node1 is 5.5.4.2 and Node2 is 5.6.0.9 Version-Release number of selected component (if applicable): 5.6.0.9 How reproducible: Steps to Reproduce: 1. Deploy idle appliances and review average cpu usage of the two processes compared over time. 2. 3. Actual results: Expected results: Additional info:
