Object Types and Object Hierarchy

The vRealize Operations Management Pack for NSX Advanced Load Balancer collects metrics and properties for several object types.

Table 1. List of Object Types

Object Types	Description
Controllers	Single point of management and control that serves as the brain of the entire system. For high availability, the controller is typically deployed as a three-node cluster. The controller implements the control plane.
Tenants	Isolated instances of the NSX Advanced Load Balancer that are associated with a user account that defines the resources that a user has access to.
Clouds	Containers for the environment that the NSX Advanced Load Balancer is installed in or operating within.
Virtual Services	Objects that advertise an IP address and ports to the external world and listen for client traffic. When the virtual service receives traffic, it can be configured for different reasons.
Pools	Objects that maintain the list of servers assigned to them and performs health monitoring, load balancing, persistence, and functions that involve NSX Advanced Load Balancer-to-server interaction.
Servers	The service engine machine. This can either be an EC2 instance/Azure Virtual Machine/Compute Instance/vCenter Virtual Machine. Note: A prerequisite to view this object type is to add the cloud account, which is, vCenter/AWS/Azure/GCP, in vRealize Operations where the service engine is deployed. This helps to monitor the actual service engine machine.
Service Engines	Machines that host the virtual services and require either direct or routable access to the client and server network.
Service Engine Groups	Objects that contain the definition of how the service engines should be sized, placed, and made highly available.
Network	Network resources used by service engines to communicate with the controller. This may be the same network as one of the data networks used for load balancing.

For more details about object types, see the Avi Documentation.

Object Hierarchy

The flow chart depicts the hierarchy of the supported objects types.

Note: When a virtual service is initially created, it is associated with the service engine group. However, when it is hosted in the service engine, it is associated with all the service engines that are hosting the virtual service.
