Description myoder 2017-01-18 16:04:20 UTC

Description of problem: 

CloudForms is generating a lot of WARN messages in the logs based on metrics it is getting from OpenShift.  The cpu usage rate average ranges from the hundreds to the thousands.  The WARN message below is the largest value I saw in the logs.

[----] W, [2017-01-17T04:50:53.711909 #28092:3d3998]  WARN -- : MIQ(ManageIQ::Providers::Kubernetes::ContainerManager::ContainerGroup#perf_process) [realtime] ManageIQ::Providers::Kubernetes::ContainerManager::C
ontainerGroup name: [logstash-5-ipi6a], id: [123000000001006] Timestamp: [2017-01-17T09:37:20Z], Column [cpu_usage_rate_average]: 'percent value 22624.395684399165 is out of range, resetting to 100.0'

Additional info:  

Currently only seeing this WARN message with 5 Container Groups and 1 Container group.  The cu environment has 11 nodes.  I am working on verifying if these Container Groups and Containers are in the same node.

In the course of about 4 hours I'm seeing 2000 log lines being generated by this message.

Please assess the importance of this issue and update the priority accordingly.  Somewhere it was missed in the bug triage process.  Please refer to https://bugzilla.redhat.com/page.cgi?id=fields.html#priority for a reminder on each priority's definition.

If it's something like a tracker bug where it doesn't matter, please set it to Low/Low.
