Figure 8 Example of the Alert Popup Window

Acknowledging an alert in either the Global Alerts view or in the alert popup window decrements

the popup counter, removes the alert from the popup window, and causes the alert to be greyed

out in the Global Alerts view. Unacknowledging an alert in the Global Alerts view restores the

alert to the popup window. The dashboard Alert notification counter appears in all controller GUI

windows.

To close the Alert popup window, click on All or on the small uparrow in the bottom center of the

Alert popup window.

Managing the Alert Policy

There is no configurable limit to the number of alerts maintained in persistent storage. Instead, the

default policy is to maintain alerts in persistent storage for 14 days, and then delete them. The

background task to delete alerts runs once a day by default. To change the policy, use the

Configurations tab in the GUI. The configuration options for maintaining alerts include:

 trim.alert.age: Specifies the number of days an alert remains in persistent storage.

Default: 14 days.

 trim.enabled: Enables or disables removal of alerts that have reached the age-out-days

limit. Default: true (enabled).

 trim.frequency: The frequency in hour per-day for trimming (deleting) alerts that have

reached the trim.alert.age limit.

Configure the Alert Age-Out Policy

Alerts cannot be selectively deleted, but are removed by an age-out policy configured in the

com.hp.sdn.adm.alert.impl.AlertManager configuration component.

1. Click on Configurations.

2. Click on the com.hp.sdn.admalert.impl.AlertManager component to display the current

Alert age-out policy.
