Map multiple business services suggested by Service Mapping

Map multiple business services suggested by Service Mapping

You can map multiple business services identified and suggested by Service Mapping in a single operation. This method suits your organization if you do not have much information about business services.

Before you begin

Role required: sm_admin

About this task

Immediately after you complete the Service Mapping setup, Service Mapping automatically creates potential business services referred to as candidates:
  1. Service Mapping extracts entries directly from load balancers on your network.

  2. Service Mapping converts load balancer entries into potential entry points.

    It also scans tables containing traffic-based connections to identify potential entry points. An entry point is the way clients access a business service. Service Mapping starts the mapping process from this point. For example, to map your electronic mailing business service, define an email address as an entry point.
  3. Service Mapping checks that potential entry points created from traffic-based connections are unique and not in use by any existing business services to avoid duplication.
  4. Service Mapping creates a business service candidate for each entry point.

    Not all candidate business services correlate to real business services. Service Mapping filters out unlikely candidates by applying an algorithm that takes into account such parameters as empty IP addresses, port numbers, and the load balancer VIP hit counts less than 1000. Service Mapping stores candidates in the Candidate Entry Point [sa_cand_entry_point] table in the CMDB.

During the discovery and mapping process, Service Mapping creates a business service from each candidate and assigns it the entry point retrieved from the candidate. While mapping in bulk is an effective and fast way to create numerous business services, the result of the bulk mapping is not precise. There may be some false or duplicate business services created by mistake because the data from the load balancer is raw. During the review and approval process, you review all mapped business services and get rid of the ones that were erroneously created.

You can further filter the list of candidates by selecting specific ones to include in or exclude from discovery. Mapping only selected candidates provides the following advantages:
  • Reduces the discovery time
  • Minimizes the number of potential irrelevant business services

You can remove the unwanted candidates from the list using these methods either by filtering them out or deleting them from the Candidate Entry Point [sa_cand_entry_point] table. In both cases, you can bring hidden or deleted candidates back to the list.

Procedure

  1. Navigate to Service Mapping > Home.
  2. Verify that Service Mapping is set up and ready for discovery.
    If some obligatory configurations are missing, the error displays at the top of the window.
    1. Click the link in the error or click the Readiness Checklist icon.

      Location of the Service Mapping Readiness Checklist icon
    2. In the Service Mapping Readiness Checklist window, click the link next to the setup category with the error icon ().
      You cannot perform discovery and mapping unless there are no errors in the Readiness Checklist window.
    3. Perform the necessary action to complete the setup.
      For example, configure missing credentials.
  3. To map all business services suggested by Service Mapping, click Map.
  4. (Optional) To map selected business services suggested by Service Mapping:
    1. Click Additional options under the Map tile.
    2. Select View Candidates List.
    3. (Optional) Display candidates based on traffic-based connections, remove the condition that filters out candidates retrieved from load balancers or imported from a CSV file.
      Display business service candidates based on traffic-based connections
      The candidate list shows candidates with the source attribute netstat.
    4. Review the list of candidates to decide which ones you want to discover as business services.
    5. Create business services from the relevant candidates:
      If you want to create business services from most of the candidates
      1. Filter out irrelevant candidates by selecting them and clicking Actions on selected rows, and then clicking Ignore Selected.

        The irrelevant candidates are hidden from the list.

        Note: To show candidates you previously filtered out, set the Ignore filtering condition to true.
      2. Alternatively, delete irrelevant candidates by selecting them and clicking Actions on selected rows, and then selecting Delete.

        The irrelevant candidates are removed from the Candidate Entry Point [sa_cand_entry_point] table containing candidates.

        Note: Service Mapping recreates deleted candidates every time Discovery performs horizontal discovery of the same load balancers or you reimport candidates from the same CSV file.
      3. Click Discover All.
      If you want to create business services only from several candidates
      1. Select the check boxes next to the relevant candidates.
      2. Click Actions on selected rows at the bottom of the screen.
      3. Click Discover selected.

    Service Mapping starts discovery of all candidates and creates business services from them. If you have many candidates, the discovery may take some time.

    After the discovery process finishes, business services, which Service Mapping discovered without errors and with at least one discovered CI, appear under the Approve tile. Business services discovered with errors appear under the Fix tile.
