It is currently not possible to add or delete nodes in a Backbone Analyst (BB/Analyst) Operations Dashboard. By default, the Backbone Analyst dashboard displays every node from which the selected tests are currently running. You can only add or remove a node from the dashboard by adding or removing a node from the tests that are displayed on the dashboard.
For information about modifying a Backbone test, see Backbone test settings in the documentation.
If you only want to see data from a few nodes, then a Backbone Operations dashboard may better suit your needs. In this view, you can select up to six nodes to display. All of the test in the account will be displayed for all of the indicated nodes.
To create a Backbone Operations dashboard, see Creating or editing operations dashboards in the documentation.
