Using filters and views to display custom event information

The alerts database tables hold event information that is forwarded to the ObjectServer. You can use filters and views to define which of this event information is displayed in your event lists.

A filter controls which alerts (or database records) can be seen, and a view controls which columns (or database fields) are visible for those alerts. You can perform information requests on the database tables using Structured Query Language (SQL).

To display alerts within the event list, it is necessary to perform a SELECT statement on the alerts.status table. The SQL statements can be separated into three conceptual parts:

Select which columns in the alerts.status table you want to view, by using views created in the View Builder.
Select the events that contain specific data values in one or more of those columns, by using filters created in the Filter Builder.
Select the order for displaying the events, by using views created in the View Builder.

The following example shows a SELECT statement that is performed on the alerts.status table:

select Node as NODE, Summary as Detail from alerts.status
where Node ='link1'

The SELECT clause is constructed within the View Builder, which is used to create and edit views. The WHERE clause is constructed within the Filter Builder, which is used to create and edit filters.
