CDM Mapping for Load Balancer nodes

LoadBalancerInstance is mapped to details on the base NetworkDevice BMC_ComputerSystem. Network devices with the Load Balancer primary capability are mapped as follows:

  • Category: "Hardware",
  • Type: "Hardware",
  • Item: "Load balancer"

The mappings for the remaining load balancer components are described in this topic.

Load balancer nodes

  • LoadBalancerService nodes are mapped to BMC_LogicalSystemComponent CIs.
  • LoadBalancerPool nodes are mapped to BMC_ResourcePool CIs.

Data models

Note

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.
Click here for reference information on impact and the data models.

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 model

CMDB versions

Effect

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.

TokenId rules

TokenId is an attribute that, in some circumstances, aids the reconciliation of CIs populated by multiple data sources. BMC Helix Discovery sets TokenId depending on the Node kind.

For most Nodes, TokenId is one of the forms:

key

or

ADDM:%key%

or

ADDM:%hashed_key%

For databases, TokenId is a database host found as a result of all possible combinations of where the database might be running:

%hosting_ci.TokenId%:%database_node.type%:%si_instance%:%database_node.instance%

and

%hosting_ci.Name%:%database_node.type%:%si_instance%:%database_node.instance%

For the Fibre Channel Node, TokenId is of the form:

WWN:%wwpn%

For physical hosts, TokenId is of the form:

%host.hostname%:%host.dns_domain%

If the domain name is unavailable, then

%host.hostname%

For virtual hosts that are running in the cloud, TokenId contains instance_id.

  • For Alibaba, TokenId is of the form:

%alibaba_instance_id%

  • For Azure, TokenId is of the form:

%azure_vm_id%

  • For AWS, TokenId is of the form:

%aws_instance_id%

  • For GCP, TokenId is of the form:

%gce_instance_id%

  • For IBM, TokenId is of the form:

%instance_id%

  • For OCI, TokenId is of the form:

%ocid%

For virtual hosts that are running in the hypervisor, TokenId contains UUID.

  • For AHV, TokenId is of the form:

AHV-UUID:%uuid%

  • For Hyper-V, the UUID is only available on the physical machine, so TokenId is only set for virtual machines that have been successfully linked to their hosting physical machines:

HYPERV-ID:%vm_uuid%

  • For KVM (including RedHat Enterprise Virtualization), TokenId is of the form:

KVM-ID:%uuid%

  • For VMware, TokenId is of the form where each letter represents a hexadecimal digit:

VI-UUID:%uuid%

  • For Xen (including Oracle VM), TokenId is of the form: 

XEN-ID:%uuid%

The following table shows how TokenId looks like for different Node Kinds:
