System Dashboard Reference

The AppLogic dashboard is the primary interface to a grid. It displays the hardware configuration and the current status of the grid, shows how many applications are currently running and how much resources are allocated to them, displays the list of currently installed applications and allows you to create, configure and manage applications.

The dashboard is a AJAX-based interface. It consists of three main tabs, named "Dashboard", "Applications" and "Support". The "Dashboard" tab provides a summary of important information about the grid, including hardware resources, operational status, and running applications. The "Editor" tab contains a list of installed applications and allows you to create, delete, copy, rename and edit applications. The "Support" tab provides useful links to 3Tera.

Dashboard

The Dashboard tab displays the grid status, including the status for each server (e.g. running, booting, shutting down, off-line), the number of currently running applications, amounts of resources reserved for them, etc. In addition, this tab displays system maintenance messages and the network settings for the grid, including available IP addresses.

Applications

The Applications tab shows you the list of installed applications on your grid, so you can select the application you would like to edit. This screen also allows you to manipulate those applications.

The following columns are shown:

(checkbox)

Selection checkbox for application operations. Select the checkbox for the application(s) you want to apply an operation on. The buttons below the list will enable and disable based on your selection, showing you what operations are allowed on the current selection.

Application Name

Unique name of the application. This is the name shown in the editor toolbar editor when you edit or view the application. This name is also used for storing the application ADL descriptors and in command-line commands for starting and stopping the application.

Description

Human-readable description of the application. The description can be modified by editing the application and opening the Application Configuration property sheet.

User 1

Free-form user-defined text intended for specifying billing code.

User 2

Free-form user-defined text intended for specifying billing code.

The application name in the table is a hyperlink -- clicking on the application name will open the application in the visual editor.

You can sort the table by clicking the column name. The arrow in the column name indicates which column is the sort column and in what order the table is sorted.

Operations

Using the buttons below the application list, you can perform operations over the selected application(s).

Edit

Opens the selected application in the visual editor, so that you can modify the application.
A faster way to edit the application is just to click on its name in the table.

View

Opens the selected application for viewing in the visual editor. In the 'view' mode, you cannot change the application; you can still inspect the application structure, see the instance settings, step into assemblies, print, etc.

Configure

Opens the application configuration property sheet for the selected application from where resources and property values of the application may be set.

New

Creates a new application. You will be prompted for a unique name for the application. Once the application is created, click on its name in the list to open it for editing.

Delete

Deletes the selected application(s). All application-specific classes (local catalog and singleton classes), as well as all volumes belonging to the application will be deleted. There is no undelete.

Rename

Rename the application. This operation changes the unique name of the application in the grid.

Copy

Makes a copy of the selected application. This operation copies all aspects of the application, including the local catalogs, singleton appliances and application volumes. This operation does not copy instance volumes, as AppLogic will create them on the first attempt to start the application.

You can see the command-line version of these operations in the AppLogic Shell command reference. There are also a few other maintenance operations that you can do with the application as a whole, which currently don't have graphical user interface. Of particular interest may be the application import and export commands that allow you to move applications between grids, as well as to archive and restore applications.

You can perform runtime control operations, such as starting and stopping the application, using the AppLogic Shell and, more specifically, the Application Control Commands.

You can delete, rename or copy an application only when the application is stopped. In all other states, the operation will fail since AppLogic has no access to application's volumes.

Support

The support tab provides useful links for accessing the AppLogic documentation, viewing and reporting bugs, access to the AppLogic Support Forum, and going to the 3Tera website.
