The Capacity Remaining score ranges between 0 (bad) and 100 (good). The badge changes its color based on
the badge score thresholds that are set by the vCenter Operations Manager administrator.

Using the Stress Badge Under the Risk Badge
The vCenter Operations Manager Stress badge measures a long-term workload that might involve undersized
virtual machines or ESX hosts or an excessive number of virtual machines. These conditions might generate
performance problems over time.
While workload is based on an instantaneous value, stress measures statistics over a longer period of time.
The Stress score helps you identify hosts and virtual machines that do not have enough resources allocated,
or hosts that are running too many virtual machines. A high Stress score does not imply a current performance
problem, but highlights potential for future performance problems.
The Stress score ranges between 0 (good) and 100 (bad). The badge changes its color based on the badge score
thresholds that are set by the vCenter Operations Manager administrator.
