Filtering alarms

Tabular information can provide an overwhelming number of records. Filtering to display only the records that interest you is an important system skill. The filtering principle used with alarms is the same for other tables.

Prerequisites: You have a table, such as an alarm console, open.

Click the Filter button () at the top of the view.
The alarm Filter window opens.
This window is context sensitive so that the available filtering controls reflect only the names and data of the columns in the currently active table view. For example, the Filter Results window contains time ranges only for tables that have a Timestamp column. You can configure filter properties by themselves or in combination. Be as precise as you can when filtering records stored in a large database. Alarm and other data grow quickly. If a query generates a table larger than 5,000 records, a message alerts you that only the first 5,000 are available for viewing.

The Last Update time controls the Timestamp column in the table.
To select records by Timestamp, enable the Last Update property (a check mark appears to the left of the property) and click the Edit Time Range button ().
The Time Picker window opens.
To change the time, enable the Start Time and End Time properties and click in each date field.
A calendar opens.
Select the date and click OK.
The system displays records that fall in a period that starts with Start Time and ends with End Time. To start at 12 am on a specific date, you will notice that the Start Time shown in the Filter Results window is the day before. In other words, the system considers midnight to be a pm time.
Configure a wildcard for text properties, such as: Source, Alarm Class, and User to equal, include, not equal or not include records.
Set any other properties for limiting the number of visible alarms and click OK.
The Filters window closes, the alarm console view includes only those alarms that meet the specifications defined by the filter, and the Filter button () changes colors.
To reset the filter, click the Filter button, click to remove the check mark(s) that identify the filter criteria and click OK.

CAUTION: Filter settings do not reset automatically when you leave the Alarm Console view. Failure to clear the alarm filter settings causes the filters to continue to hide (or filter) alarms, which do not appear in the alarm console until you clear the filter settings.
