Creating a connectivity chain

To create a connectivity chain:

  1. In the Correlation module, go to the connectivity editor tab, and click Launch connectivity editor.

    The connectivity editor will be opened in a separate window.

  2. In the Connectivity Editor window:

    • Click File > New Element Chain to create an element chain.

    • Click File > New Internal Service Chain to create an element chain within a service.

    • Click File > New Service Chain to create a service chain.

  3. Drag and drop elements or services to the pane on the right.

  4. Make a topology connection between elements or services:

    • Right-click an element or service and select Link or Unlink, or

    • Drag and drop while pressing the Ctrl key.

      Note

      If you use the drag-and-drop functionality to link the items in a chain, you must drag to the top or bottom border of items. The direction of the link depends on whether you choose the top or bottom border. Dragging to the top border creates a link from the dragged item to the target item, dragging to the bottom border creates a link to the dragged item from the target item.

  5. Optionally, narrow down the possible causes for an element or service by selecting only some of its parameters:

    1. Right-click the element and select Select Parameters.

    2. Select the option Include a SELECTION of parameters.

    3. Select the parameters in the Available list, and move them to the Included list with the < button.

      Note

      Only monitored parameters are available in this window.

    4. Click OK. The included parameters are now indicated on the item in the chain.

  6. If necessary, click the Options button in the lower right corner to configure the following options for the chain:

    • Require alarms to occur on consecutive elements in the chain ... : If this option is selected, the RCA level is reset if the parent element is not in alarm, even if other elements are in alarm higher up in the chain.

    • Use unique RCA levels when multiple parameters are combined ... : If this option is selected, and a block contains multiple parameters, a different RCA level is applied for parameters in that same block. The first parameter that triggers an alarm can for example get RCA level 0, the next one level 1, etc.

  7. When all necessary items have been added and linked, click the Save button.
