How to Design Topologies

This section describes how to design a topology that graphically displays the logical components that make up your application under test (AUT) and the relationships between the components. This provides a useful method for managing your inventory of AUT hosts and enables topology-oriented monitoring and analysis.

Note:

  • This task is part of a higher-level task. For details, see Manage Testing Assets.

  • Ensure that SiteScope is installed and configured to integrate with Performance Center. For details, see the section about installing SiteScope in the Performance Center Installation Guide.

  • After you have designed a topology you can select it for a performance test when you design the test.

Tip: For a use-case scenario related to this task, see How to Design Topologies - Use-Case Scenario.

To design topologies

  1. Create an empty topology

    1. On the My Performance Center navigation bar, select Resources > Topologies.

    2. To create a topology folder, click the New Folder button, and enter the folder name.

    3. Click the New Topology button and enter the topology details. To add SiteScope monitors to the topology, specify the SiteScope server details.

  2. Design the topology

    Note: The Topology Designer window opens automatically when you create a new topology. If the Topology Designer window did not open, select a topology and click Design Topology.

    In the Topology Designer window:

    1. From the palette on the left, select relevant nodes representing the components in your AUT and drag them onto the Topology canvas.

    2. To connect two components, click one component (ensure that it is not selected) and drag the cursor to the other component.

  3. Add the AUT hosts

    Define the machines that host the relevant components of the AUT.

    On the Topology Designer window, click AUT Hosts. Click Add New AUT Host to define the machines hosting your AUT.

    Tip: If you have an Excel file listing your AUT hosts, you can import the list of AUT hosts into ALM. For details, see the ALM Lab Management Guide in the ALM Help Center.

    You can view the list of AUT hosts in the AUT Hosts tab on the left.

  4. Configure the component properties

    Select a component and, in the Properties pane in the top right corner of the Topology Designer, enter the relevant properties for that component. For successful integration with SiteScope, ensure that you select the relevant AUT host, and that all of the relevant properties are accurate.

    Tip: When you click a property, a description is displayed in the lower area of the Properties pane.

    Repeat this procedure for each of the relevant components.

  5. Configure monitors on the components

    You can configure groups of monitors for the components on AUT hosts. Ensure that the AUT host details are accurate for each relevant component.

    • To deploy relevant monitors on specific components on your canvas, select the components, right-click the selection, and select Deploy Monitor Templates. Monitor groups are created in SiteScope for each selected component, and each group is automatically configured with relevant system-defined monitors.

    • To configure monitors for a component manually in SiteScope, right-click the component and select Configure Monitors. For more details about configuring monitors in SiteScope, see the SiteScope User Guide available from the Software Documentation Portal at https://docs.microfocus.com/.

    • Note: The AUT host defined in a component's properties is passed to SiteScope as a remote host and is inserted as the default monitored server for all monitors created for this component.

  6. Results

    After you save the topology, you can select the designed topology for your performance test. For details, see Performance Test Designer > Topology.

    During a test run, you can view the SiteScope monitor activity on the relevant components in your AUT. For details, see Performance Test Run Page (Online Screen).
