---------------------------------------

             Summary: Fix high CPU deviation seen in Zone/Cluster metrics view
                 Key: CLOUDSTACK-9900
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9900
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
            Reporter: Rohit Yadav
            Assignee: Rohit Yadav
             Fix For: Future, 4.10.0.0, 4.9.3.0


High CPU deviation (100-400%) is seen in the metrics view. The regression was caused becase HostStats returns CPU usage in percentage and memory usage in bytes, while the deviation calculation method did not assume that passed values are in percentage and multiples the ratios by 100 resulting in 100x the actual values.
