Calculate Application Dependencies

The Calculate Apps button on the Inventory tab starts a process that determines interdependencies related to selected applications in the environment. The information is displayed in multiple ways on various pages in the UI to allow you to identify potential risks and establish priorities for moving the data.

Some application mapping was probably done prior to import. But, users can also create or customize applications in the Virtana Platform by adding and removing compute instances on the Inventory page. Once your applications are set, you can run an application dependency analysis to determine how your applications are related.

Prerequisites

Before calculating application dependencies, you should have verified that import of the project archive file produced the expected results. See Verify the Project Import.

Steps

  1. Navigate to the Inventory tab.

  2. Select the move groups to calculate.

    Do one of the following:

    • Click Calculate All Applications.

    • Click the checkbox next to a move group, and then click Calculate 1 Application.

    • Click checkboxes next to multiple move groups and then click Calculate for n Application(s).

    The number of items selected displays in the column footer and on the Calculate button.

    A message momentarily displays in the lower left, indicating the status of the calculation.

    The page becomes inaccessible while the calculations are being performed. You can still access other areas of the software, but be sure to return to this page and save the calculations.

    Depending on the objects in the group, the calculation can take awhile.

  3. When the calculation completes, click Save.

    The page becomes inaccessible while the calculations are being performed. You can still access other areas of the software, but be sure to return to this page and save the calculations.

    Ensure you save after the calculations complete, to retain the calculations.

  4. Navigate to Applications > Application List.

    Use the information to verify that the application was added and that the correct objects are in the application.

  5. Click on Applications > Analysis Summary.

    Use this information to assess dependencies between applications and compute instances, and determine if changes need to be made to applications to reduce move risks.
