Alert Viewer
The ALERT VIEWER portlet allows users to view alerts defined for the system. The alert information in the summary view is updated every 30 seconds. Every alert has a timestamp, displaying the date and time at which the alert was issued.
You can filter the alerts by for example severity, time period, type, or name. You can also combine the filters to narrow the results further.
The ALERT DETAILS view provides detailed information about what triggered the alert, the source of the alert, and any relevant messages.
About Alerts
An alert is an event that your Teradata System Administrator defined as being significant.
The Teradata System Administrator assigns alert severity to rank alerts; critical, high, medium, or low, and can also provide an explanatory message. The alerts displayed in the
ALERT VIEWER are specific to your system.
Common Alert Example
The Teradata System Administrator can define that a database exceeding a certain amount of used storage, triggers an alert. This alert appears in the ALERT VIEWER with details that assist in performing cleanup before the database is full.

About Filters and Sorting
Filters allow you to change displayed data by only showing rows that match your filter criteria. You can sort the information in the columns. Filtering allows you to:
• Click in a filter box, start typing, and then press Enter. The value you enter appears in bold. After the view refreshes, only the information matching the value you entered is displayed.
• Narrow your search further by filtering on multiple columns in succession.
Sorting allows you to:
• Sort on a column by clicking the column heading. A second click sorts in descending order.
• Sort two columns consecutively. Primary sort order is indicated by a dark blue column heading, and secondary sort order is indicated by a light blue column heading.
• Sort in ascending or descending order on all pages when there are multiple pages.
The filtering, sorting, and page number settings that you choose for the default or minimized display do not persist when you switch to the maximized display.
