BMC Atrium Discovery enables you to discover load balancer instances and their configuration. The resulting inferred model shows how the load balancer components relate to each other. You can discover dedicated hardware load balancers such as Application Delivery Controllers from F5 or Citrix (NetScaler), or the virtualized versions of these devices. 

Network device node (load balancer)

BMC Atrium Discovery can now discover and model the load balancing configuration for certain NetworkDevice nodes that were previously displayed with a Type of Layer 3 Switch.

Load balancer information is discovered using SNMP. When BMC Atrium Discovery finds a hardware or virtualized Application Delivery Controller (ADC) that has load balancer options enabled, it creates a network device node and triggers the load balancer discovery TPL patterns to query the necessary information about the related load balancing components, including pools, hosts and services. As soon as these elements are discovered, the following nodes (with relationships) are modeled, where applicable: 

  • Load Balancer Group
  • Load Balancer Instance
  • Load Balancer Service
  • Load Balancer Pool
  • Load Balancer Member 


The node details page for a  NetworkDevice node representing a load balancer has an additional Services section. The discovered objects specific to load balancers are listed in the table below.

Field name

Details

Instances

A logical load balancer instance representing the load balancing module running on the device.

Services

A load balancing service that is used for incoming connections to a load balancer.

Pools

Pools containing members; when pools are not used, a "default" placeholder pool node is created.

Members

Connection to physical servers linked to the load balancer (in <ip address>:<port> format).

Hosts

Hosts connected to the load balancer.
