Hi Aviv, please review this doc text:
Previously, the VM memory/CPU overcommit panels in the Ovirt Executive Dashboard/Cluster Dashboard displayed the average memory for a single hypervisor and the average memory of all virtual machines in a cluster.
In this release, the dashboard panels show the correct overcommit rates between all the hosts in the cluster and all the virtual machines in the cluster.
The Cluster VM CPU and Memory Overcommit panels (EX03-9 and EX03-10) under oVirt Executive Dashboards/03 Cluster Dashboard
now sum the memory and CPUs of all hosts in the cluster.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory (RHV Manager (ovirt-engine) [ovirt-4.4.10]), and where to find the updated
files, follow the link below.
If the solution does not work for you, open a new bug report.
