Create an infrastructure relationship for related CIs

Infrastructure relationships show CIs that are connected to a business service but are not necessary parts of the service. Infrastructure relationships are only available for business services.

About this task

When you create a CI infrastructure relationship, the information is stored in the Infrastructure Relations [em_impact_infra_rel_def] table. When alerts generate, the related CI accompanies the business service information on the Event Management dashboard and in the impact tree. Additional information for the related CIs only appears on a related dependency views map for the business service. The following default infrastructure relationships are available.
Table 1. Default infrastructure relationships
Infrastructure relationship Impact rule Description
cmdb_ci_appl Host in Cluster Shows alert impact between hardware and software applications.
cmdb_ci_esx_server Containment Shows alert impact between VCenter and ESX clusters.
cmdb_ci_kvm Containment Shows alert impact on Linux Kernel-based Virtual Machine (KVM) connectivity.
cmdb_ci_vm_zones Containment Shows alert impact on the Solaris VM zones.
For example, based on of the cmdb_ci_vm_zones Infrastructure relationship definition, Event Management adds ZoneServer@mmp1 to the business service. The Containment rule manages impact severity on alerts.

Procedure

  1. Navigate to Event Management > Settings > Infrastructure Relations.
  2. Click New.
  3. Fill in the fields, as appropriate.
    Table 2. Infrastructure Relations form
    Field Description
    Child Type The table that contains data about the child entity.
    Parent Type The table that contains data about the parent entity.
    Relation Type The relationship between the child and parent entities.
    Impact Direction The impacts direction to show on the business service map.
    • From Child to Parent: When an alert is regarding a child, show the impact on the parent.
    • From Parent to Child: When an alert is regarding a parent, show the impact on the child entity.
    Impact Rule The impact rule to calculate infrastructure relationships:
    • Host in Cluster: Determines how host cluster members affect the overall cluster status based on a percentage or number of cluster members. For example, if a three-host cluster requires 50% Influence to set the severity of Major, each member has 17% Influence (50% divided by 3). The severity of the entire cluster can only change to Major when two or more cluster members have a severity of Major. The entire cluster is also considered to be down.
    • Cluster Member Influence: Determines how application cluster members affect the overall impact of the cluster. For example, if a three-member cluster requires 70% Influence to set the severity for the entire cluster to Major, each member has 23% Influence (70% divided by 3). The severity of the entire cluster can only change to Major when all three members have a severity of Major.
    • Containment: Determines the definition of impact propagation for CIs in infrastructure relationships.
    • CI Business Service: Determines how impact applies to parent or child entities that are part of a business service.
    • CI Parent in Application: Sets impact only on the parent entity.
    • Inclusion: Determines the impact on entities with a Contains relationship. This rule is read-only.
    • Network Path: Determines how impact applies to parent or child entities that are part of a traditional network.
    • Storage Path: Determines how impact applies to parent or child entities that are part of a storage network.
    • Service Members: Applies to manual services. Determines the relationship between service members. The impact from child to parent CIs is always 100%. For example, the parent impact severity is derived from the child CI with the highest severity.
