Use a Legacy BSM map How to use a Legacy Business Service Management (BSM) map. A business service management (BSM) map has one starting point, called the root CI or root node of the map. The root CI is highlighted with a circle around it. The maps can show both upstream and downstream dependencies for the root CI. By default the BSM map displays 3 levels, both upstream and downstream relationships, and collapses all clusters. Administrators can configure the number of levels displayed. Use the layout controls to display map elements in different configurations for easier management. Use the filter panel to display fewer levels or to filter out elements you don't want to see, then save the filter for use later. Draw new relationships between elements or edit existing relationships. In a BSM map, icons and glyphs indicate if a CI has an active, pending issue. You can investigate the tasks that are connected to a CI to get more details. The map collapses and expands clusters to make them easier to view.
