Each policy includes a package of symptom definitions. Each symptom represents a distinct test condition on a property, metric, or event. You can activate or deactivate the symptom definitions in your policy.
How the Policy Symptom Definitions Work
VMware Aria Operations uses symptoms that are activated to generate alerts. When the symptoms used in an alert definition are true, and the alert is activated, an alert is generated.
When a symptom exists for an object, the problem exists and requires that you take action to solve it. When an alert occurs, VMware Aria Operations presents the triggering symptoms, so that you can evaluate the object in your environment, and with recommendations for how to resolve the alert.
To assess objects for symptoms, you can include symptoms packages in your policy for metrics and super metrics, properties, message events, and faults. You can activate or deactivate the symptoms to determine the criteria that the policy uses to assess and evaluate the data collected from the objects to which the policy applies. You can also override the threshold, criticality, wait cycles, and cancel cycles.
The Symptoms pane displays the name of the symptom, the associated management pack adapter, object type, metric or property type, a definition of the trigger such as for CPU usage, the state of the symptom, and the trigger condition. To view a specific set of symptoms in the package, you can select the adapter type, object type, metric or property type, and the state of the symptom.
When a symptom is required by an alert, the state of the symptom is activated, but is dimmed so that you cannot modify it. The state of a required symptom includes an information icon that you can hover over to identify the alert that required this symptom.
Where You Modify the Policy Symptom Definitions
To modify the policy package of symptoms, from the left menu click Add to add a policy or select the required policy. In the right pane, click Edit Policy to edit a policy. In the Create or Edit policies workspace, click Alerts and Symptoms. The alert definitions and symptom definitions for the selected object types appear in the workspace., and then click
|Object Type||Select an object type to view the symptom definitions list by the selected object type.|
Limits the list based on the text you type.
You can also filter by:
|Actions||Select one or more symptom definitions and select activate, deactivate, or inherit to change the state for this policy.|
|Page Size||The number of symptom definitions to list per page.|
|Symptom Definitions data grid||
Displays information about the symptom definitions for the object types. The full name for Symptom Definition appears in a tooltip when you hover the mouse over the Symptom Definition name.
If you do not configure the package, the policy inherits the settings from the selected base policy.
