Predefined alerts are provided in
VMware Aria
Operations
as part of
your configured adapters. Use Alert Definitions to manage your VMware Aria
Operations
alert
library, and to add or modify the definitions.- Modifying Alert Definitions
- If you modify the alert impact type of an alert definition, any alerts that are already generated will have the previous impact level. Any new alerts will be at the new impact level. If you want to reset all the generated alerts to the new level, cancel the old alerts. If they are generated after cancellation, they will have the new impact level.
- Symptoms in Alert Definitions
- Symptom definitions evaluate conditions in your environment that, if the conditions become true, trigger a symptom and can result in a generated alert. You can add symptom definitions that are based on metrics or super metrics, properties, message events, fault events, or metric events. You can create a symptom definition as you create an alert definition or as an individual item in the appropriate symptom definition list.
- When you add a symptom definition to an alert definition, it becomes a part of a symptom set. A symptom set is the combination of the defined symptom with the argument that determines when the symptom condition becomes true.
- An alert definition comprises one or more symptom sets. If an alert definition requires all of the symptom sets to be triggered before generating an alert, and only one symptom set is triggered, an alert is not generated. If the alert definition requires only one of several symptom sets to be triggered, then the alert is generated even though the other symptom sets were not triggered.
- Recommendations in Alert Definitions
- Recommendations are the remediation options that you provide to your users to resolve the problems that the generated alert indicates.
- When you add an alert definition that indicates a problem with objects in your monitored environment, add a relevant recommendation. Recommendations can be instructions to your users, links to other information or instruction sources, orVMware Aria Operationsactions that run on the target systems.
