Fix errors in individual application services using discovery messages

Service Mapping does not offer semi-automated resolution options for errors that require advanced resolution. Fix such errors using symptoms and discovery messages.

Before you begin

Try fixing errors using semi-automated resolution options as described in Fix errors in individual application service maps.

Role required: sm_admin

About this task

You can fix errors in individual application services at any time.

Procedure

  1. Navigate to Service Mapping > Services > Application Services.
  2. Click View Map next to the relevant application service.
  3. Ensure that the map opens in Edit mode.

    Discovery messages appear below the map.
    CIs discovered with errors appear with the warning icon (The Warning icon) on the map. Discovery messages on the Discovery Messages tab give short error descriptions.
  4. Fix errors based on the symptoms and discovery messages.

The rest of the CIs also disappear from the map. KB0621529: Resolving the issue of a load balancer disappearing from the business service map
    • The application service map displays the warning icon (The Warning icon) on top or instead of the configuration item.

    A CI or a segment of the map is grayed out after Service Mapping runs the top-down discovery on a previously mapped application service.

    In this business service Service Mapping failed to rediscover the CI or connections leading to this CI.

    1. (Optional for grayed out segments) Identify the faulty CI that causes the segment to be grayed out.
    2. Use the discovery message associated with this faulty CI to resolve the problem.
  5. Click Run Discovery.
