Chapter 14 Dataviews
This chapter provides the following information:
Overview of Dataviews
Dataviews are customized data property tables. You can create dataviews
for any of the following data:
-
One type of data from several different hosts within a single domain
-
Several types of data from one host
-
Several types of data from different hosts within a single domain
An example of the first concept is a dataview that monitors CPU usage in group
of hosts. An example of the second concept is a dataview that monitors disk space
and CPU usage on one host.
Note –
Dataviews allow you to combine information from different hosts within
a Sun Management Center domain; however, you cannot create a dataview that combines data from
different domains.
Dataview Contents
The data that is used to create a dataview is copied from different sources,
including:
Dataviews are an excellent way of monitoring a collection of unrelated information.
Because these views are presented in a table, a variety of data can be easily compared.
Dataviews are created once and are refreshed automatically. Dataviews have all the
features of module tables, except that cells cannot be edited. In dataviews, alarm
status is correctly propagated. Cells that have triggered a critical alarm appear
in red.
When you create a dataview, the dataview is stored in the database. The dataview
persists until you explicitly delete the dataview. In addition, because dataviews
are stored in the database, dataviews can be shared. Any dataview that is built on
a particular Sun Management Center server can be viewed by all authorized users on that server.
Navigating Through a Dataview Window
The dataview window contains the following main menu items:
-
File, which enables you to save the current dataview to a name or
to close the current dataview
-
Edit, which enables you to paste a dataview from the clipboard or
to delete selected rows
-
Tools, which provides direct access to the Attribute Editor for the
selected cell
-
Help, which displays online help

Types of Dataviews
There are two types of Dataviews:
Scalar Dataviews
A scalar dataview is created from scalar data items, which are single
cells from scalar or vector tables. A scalar dataview includes the following three
columns:
To Create a Scalar Dataview
The following example uses the CPU Utilization table.
-
In the Details window, navigate to the CPU Utilization
table.
-
Select a data cell in the table.
-
Copy the data cell to the dataview clipboard
in either of the following ways:
-
From the Options menu, choose Copy to Dataview Clipboard Cell(s) or
Create Dataview Cell(s).
-
In the Details window, press mouse button 3 on the table and select
Copy to Dataview Clipboard Cell(s) from the pop-up menu.
For additional information about the Copy to Dataview Clipboard and the Create
Dataview options, see Creating a Dataview.
Vector Dataviews
The vector dataview contains one or more rows from a vector module table.
You can simultaneously select one row or multiple rows from a vector table. You can
select multiple rows that are not contiguous. For example, you could select the following
rows:
-
Row number 1
-
Row number 3
-
Row number 4
-
Row number 6
You cannot select partial rows.
Caution –
Do not paste rows from vector and scalar tables into the same dataview
window.
To Create a Vector Dataview
The following example uses the CPU Utilization table.
-
In the Browser Details window, navigate to the
CPU Utilization table.
-
Select a row in the table.
Tip –
To select multiple rows in the table, use the Shift key. To select multiple,
non-continuous rows from the table, use the Control key.
-
To copy the data rows to the dataview clipboard,
proceed with one of the following:
-
From the Options menu, choose Copy to Dataview Clipboard Row(s) or
Create Dataview Row(s).
-
In the Details window, press mouse button 3 on the table and select
Copy to Dataview Clipboard Row(s).
For additional information about the Copy to Dataview Clipboard and the Create
Dataview options, see Creating a Dataview.
Caution – You can only paste compatible data types. If you try to paste an incompatible
data type, an error dialog box appears.
