The Stress tab indicates represents how vRealize Operations Manager calculates how much an object demands over a period of time. This analysis compares an object's workload against its capacity. 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.

Stress accumulates when workload exceeds the specified stress line. The Stress score is the percentage of the stress zone area with stress in your selected time sample. A high Stress score does not imply a current performance problem, but highlights potential for future performance problems.

The Stress Badge

The Stress score ranges between 0 (good) and 100 (bad). The badge score thresholds can by modified by the vRealize Operations Manager administrator.

See Policies to configure symptom thresholds for the Stress badge score.
