Metric and super metric symptoms are based on the operational or performance values that vRealize Operations Manager collects from target objects in your environment. You can configure the symptoms to evaluate static thresholds or dynamic thresholds.

You define symptoms based on metrics so that you can create alert definitions that let you know when the performance of an object in your environment is adversely affected.

Static Thresholds

Metric symptoms that are based on a static threshold compare the currently collected metric value against the fixed value you configure in the symptom definition.

For example, you can configure a static metric symptom where, when the virtual machine CPU workload is greater than 90, a critical symptom is triggered.

Dynamic Thresholds

Metric symptoms that are based on dynamic thresholds compare the currently collected metric value against the trend identified by vRealize Operations Manager, evaluating whether the current value is above, below, or generally outside the trend.

For example, you can configure a dynamic metric symptom where, when the virtual machine CPU workload is above the trended normal value, a critical symptom is triggered.
