An alert is an event that the Teradata System Administrator defines as significant. The Teradata System Administrator assigns alert severity levels to rank alerts, and can also include a message. The severity levels are critical, high, medium, or low. The alerts displayed in the Alert Viewer portlet are specific to your system.
Alert Example
The Teradata System Administrator can define that a database exceeding a certain amount of storage usage triggers an alert. After the usage level is exceeded, an alert appears in the Alert Viewer portlet to inform the portlet user that the threshold was exceeded.
