The Object Viewer monitors the status of the objects and their attributes and can be used to modify an attribute value for testing purposes. See Object Viewer overview in the Application Server help for detailed information.

Start Object Viewer

Note: Advanced diagnostic mode can only be accessed when Object Viewer is started from a command prompt.

From the IDE

  • Select a deployed object, then select Object Viewer, located in the Home ribbon Runtime group

    or

  • Right-click a deployed object, and select View in Object Viewer from the Context menu.

From the Windows Start menu

From the Operations Control Management Console

In the console tree, expand the Platform Manager to show the list of Galaxies, and then expand a Galaxy to show a list of platforms. Right-click the desired platform, and select Launch Object Viewer.

From a command prompt

In a command prompt, navigate to:

C:\Program Files (x86)\ArchestrA\Framework\Bin

Enter the command:

aaObjectViewer.exe

To start Object Viewer in advanced diagnostic mode, enter:

aaObjectViewer.exe /New

Add object to the Watch List

To add an object to the Object Viewer Watch list, you can manually type the object and attribute names into the attribute reference box in the menu bar and select Go. When prompted to enter the Attribute Type, select OK.

You can save a list of items being monitored. Once you have a list of attributes in the Watch Window, you can select all or some of them and save them to an XML file. Right-click on the Watch window to save the selection or load an existing one. You can also add a second Watch window that shows as a separate tab in the bottom of the Viewer.

Note: Do not use Ctrl + S to save the Watch window. Instead of saving the Watch window, this key combination will instead create an empty file.

Refer to the platform and engine object help for information about attributes that may indicate system health. These attributes provide alarm and statistics on how much load a platform or engine may have when executing application objects or communicating with I/O servers and other platforms.
