Tutorial 3: Adding Views 61

Designing the Page

The objectives for Tutorial 3 have listed the components we are going to use, so all that

needs to be done to design the page is to specify its layout. The table below shows how

the components will be arranged.

My Hosts dependent page for Tutorial 3: a Grid layout with two columns

Defining the Alarms Query

The drilldown page is going to display information about the alarms on a chosen host,

so a query is an obvious choice for getting the required data. However, the data retrieved

by the query should be for a specific host, but the host is only chosen at run time as a

result of user interaction. The solution is to use a parameterized query. The parameter’s

value will be assigned at run time by selecting a row in the My Hosts table.

Above the grid

A Customizer that places itself above

and to the left of the View and Help

buttons on the title bar.

Row 0, Column 0:

Host State: A Key-Value Listing

component.

Row 0, Column 1:

Memory - Utilization History:

A chart component.

Row 1, Columns 1 and 0 spanned:

Alarms table for <host>:

A Row-Oriented Table listing alarms for the chosen host.

The component will span two columns of the Grid container, similar to this row.

Row 2, Column 0:

Return to Hosts Page T3:

A Label component (with a flow action

that returns to the parent page).

Row 2, Column 1:

Host Chooser DDL T3:

A Drop-Down List component (whose

flow action is Update, which permits

choosing a new host. The current page

updates itself with new information

based on the chosen host.)
