You can use global alert settings to specify immediate global control of alert processing.

There are three categories of control that you have over alerts.

Alerts

You can enable or disable all alert definitions for all resources immediately. Disabling stops any alerts from being triggered.

Notifications that have been defined in escalations that are currently in progress are completed.

Alert Notifications

You can enable or disable alert notifications for all resources immediately. Disabling stops all notifications, including those for alerts with escalations currently in progress.

Hierarchical Alerting

The purpose of hierarchical alerting is to avoid triggering alerts for every resource affected by a single root cause.

This setting controls whether alerts are evaluated using the hierarchical alerting method. When hierarchical alerting is enabled, before an alert is triggered for a resource, vRealize Hyperic considers the availability and alert status of the resource's parent.

You can extend the effect of hierarchical alerting by configuring the relationship between a network device or virtual host and the platforms that depend on it, using the Network and Host Dependency Manager.
