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 "Applications" tab contains a list of installed applications and allows you to create, delete, copy, rename, start, stop, and edit applications. The "Support" tab provides useful links to 3Tera.

Dashboard

The Dashboard tab displays the grid status, high availability status, the number of currently running applications, amounts of resources reserved for them, whether resource oversubscription is enabled, etc. In addition, this tab displays system maintenance messages and the network settings for the grid, including available IP addresses that can be used for applications running on this grid.

Operations

Using the buttons below the grid status you can perform operations:

Grid Login

Opens a command line shell through which commands may be executed. See Command Line Shell Reference for more information.

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:

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.
The shown next to an application name designates the application as being locked. When the application is locked, it may not be edited or viewed within the Editor. See the Application and Class locking Reference for more information.

State

State of the application. When an application is started, stopped, restarted, or copied, the status of the operation is shown here. See Application Status for more information.

Description

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

CPU

Amount of CPU resources required by the application. If the application is currently running, this value specifies the amount of CPU resources allocated to the application.

Mem

Amount of Memory resources required by the application. If the application is currently running, this value specifies the amount of memory resources allocated to the application.

BW

Amount of Bandwidth resources required by the application. If the application is currently running, the value specifies the amount of bandwidth resources allocated to the application.

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.

Toolbar Operations

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

Start application

Starts the selected application.

Stop application

Stops the selected application.

Restart application

Restarts the selected application.

Edit application

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 application

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 application

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

Grid Shell

Opens a command line shell through which commands may be executed. If there is an application selected, the application is set as the current application within the shell. See Command Line Shell Reference for more information.

Login(ssh)

Login to the selected application's default appliance via SSH (SSH console). This operation is available only if the application is running, has a configured default appliance, and that appliance supports SSH access.

Login(web)

Login to the selected application's default appliance web interface. This operation is available only if the application is running, has a configured default appliance, and that appliance exposes a web interface.

Login(text)

Access the text boot console for the selected application's default appliance. This operation is available only if the application is not stopped, has a configured default appliance, and that appliance exposes a text console.

Logn(graphic)

Access the graphic console for the selected application's default appliance. This operation is available only if the application is not stopped, has a configured default appliance, and that appliance exposes a graphic console.

Monitor application

Opens the application monitoring user interface for the selected application from where the application performance and resource utilization statistics may be viewed.

Provision application

Provision the selected template application. Opens the Application Provisioning Wizard from where the provisioned application name and other configuration parameters may be set.

Migrate from

Migrate an application from a remote grid. Opens the Application Migration Wizard from where the remote grid as well as other configuration parameters may be set.

Migrate to

Migrate an application to a remote grid. Opens the Application Migration Wizard from where the remote grid as well as other configuration parameters may be set.

New application

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 application

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 application

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

Copy application

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.

Application Documentation

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 run time 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.

Context Menu Operations

The following operations are available via a context menu when you select an application and press the right mouse button:

Start

Start the selected application.

Stop

Stop the selected application.

Restart

Restart the selected application.
