In SCVMM the overcommit status is not clear althought there is an article from VMM 2012 R2:
https://support.microsoft.com/en-us/help/3023928/details-of-the-cluster-overcommit-algorithm-in-system-center-2012-r2-v

Is very important to have a visual / graphical feedback on the overcommitment status.
Example :
In the Cluster properties / General we could have a description like:

Not enought Memory to assign more VM's;
Overall CPU consumption over XX%;
