BMC Discovery 11.3 ... Integrating CMDB synchronization Default CDM Mapping CDM Mapping for Network Device

CDM Mapping for Load Balancer nodes

LoadBalancerInstance nodes are mapped to details on the base Network Device. The mappings for the remaining load balancer components are described in this topic.

Load balancer nodes

  •  LoadBalancerInstance nodes are mapped to details on the base Network Device.

  •  LoadBalancerService nodes are mapped to BMC_LogicalSystemComponent CIs.

  •  LoadBalancerPool nodes are mapped to BMC_ResourcePool CIs.

Data models

CMDB version differences

The default mapping works with CMDB versions 7.5, 7.6, and 7.6.03 and later. The data model in each is slightly different.

  • BMC_Impact relationships are not normally created with CMDB 7.6.03 and later, since the CMDB automatically maintains them itself. See the information about impact relationships for more details.

Different versions of the CMDB have subtly different data models. Syncmappings can support multiple data models with datamodel declarations. CMDB data models are assigned simple integer values:

Data modelCMDB versionsEffect

6

7.6.03 and later

HasImpact and ImpactDirection attributes are set as appropriate.

5

7.6.03 and later

Only to be used with legacy SIM version 7.4. BMC_Impact relationships with Name “ImpactOnly” are created.

4

7.6.03 and later

No impact details are set by BMC Discovery. They may be set by Impact Normalization in the CMDB.

3

7.6 before 7.6.03

BMC_Impact relationships with name “IMPACT” are created.

2

7.5

BMC_Impact relationships with name “IMPACT” are created.

BMC_LogicalSystemComponent

LoadBalancerService nodes are mapped to BMC_LogicalSystemComponent CIs.

Details

TokenId

Attribute that aids reconciliation of CIs populated by multiple data sources. TokenId is of the form "ADDM:hashedkey", where hashedkey is a hash of the LoadBalancerService key.

Name

Load Balancer Service name or
Load Balancer Service name : computersystem name if the target is Remedyforce.
