If Service Mapping erroneously mapped some CIs as part of an application service, remove these CIs for noise reduction. It is important to remove unnecessary CIs from the map, because they can generate irrelevant alerts in Event Management. For example, when creating an application service for a web portal, Service Mapping may automatically discover a connection to external services, such as PayPal service, that do not belong to the service.

1. Navigate to Service Mapping > Services > Application services.
2. Click View map next to the relevant application service.
3. To remove CIs, right-click the connector leading to the CI you want to remove, and select Mark boundary.
   The CI is marked as boundary on the map ().
4. To remove CIs discovered using traffic-based discovery, perform the following steps:
   1. Right-click the CI on the map.
      Note: You can see traffic-based connections for a CI, even if you disabled the traffic-based discovery for an application service the CI is part of.
   2. Select Show traffic based connections.
      The Traffic Based Connections List opens displaying the following information:

      Table 1. Traffic Based Connections List

      Field	Description
      IP	The IP address of the application connected to the selected CI.
      Port	The port on the selected CI that is used to communicate to the other application.
      Process	The ID of the process in the selected CI.
      Already on map	Yes — if this connection shows on the map. No — if this connection is not part of the application service and not on the map.
      System decision	The setting defines if Service Mapping keeps the discovered traffic-based connection or removes it. The value comes from the algorithm that Service Mapping uses.
      User decision	(Optional) The setting overrides the System decision setting, which defines if Service Mapping keeps the discovered traffic-based connection or removes it. For example, if the System decision setting for a connection is Keep, and you want to remove this connection, select Remove.

      Note: There may be a case when you can see traffic-based connections on the map, but the Traffic Based Connections list does not display them. It happens for the connections that have been removed from the TCP Connection [cmdb_tcp] table less than three days.
   3. In the Traffic Based Connections List, identify the connection used to discover the unwanted CI.
   4. Select Remove from the User decision field for this connection.
   5. Click Close.
