Notifications
Configure an alert to fire a notification when it is lowered or raised or is active.
You can configure the way an alert sends notifications of status changes on the
Notifications tab.
The status of every alert is evaluated automatically as new data is collected by
Virtualization Manager. If you set up an alert to evaluate on performance data, the
evaluation happens every time new performance data is collected (10 minutes by
default). If you set up an alert to evaluate on configuration data, the evaluation
happens every time new configuration data is collected (12 hours by default).
You can also evaluate an alert manually by saving your changes on the alert
configuration page, or by clicking Evaluate now on the alert details page.
If you want to receive the notification every time the alert status is raised, lowered,
or active, select Notify on consecutive events. Otherwise, select Notify only
when raised. This way, Virtualization Manager only sends a notification when the
alert is raised.
Each alert has the following four statuses:
l Inactive
l Raised
l Active
l Lowered
The following table describes when an email notification is sent with the different
options selected.
