GitHub user weizhouapache edited a comment on the discussion: Dashboard 4.19.2. 
New Used/Allocated resources view ???

@SviridoffA 
The values are fetched via cloudstack API, it is not a UI issue.

Moreover, I think it is not a bug. for clarification

- On the dashboard boarding page, data are fetched by API listCapacity
  - Allocated capacity: the resource allocated to the user vms and system vms, 
etc
  - Used capacity: the resource used by Running vms, or reserved for vms which 
are stopped recently

- On the Cluster/Zone details page, data are fetched by API listZonesMetrics or 
listClustersMetrics
  - Used: the real usage of hosts in the zone or cluster. It is consistent with 
the usage users get on the host (for example, free, htop, uptime)
  - Allocated: the resource used by Running vms, or reserved for vms which are 
stopped recently (same to Used capacity above) in precentage
  - if the used percentage is much smalled than Allocated percentage, it means 
you could allocate more resources on the environment. You can increase the over 
provisioning factor (be careful on MEMORY if you use KVM).
