Load balancer stream attributes
Entuity Load Balancer includes an extensive breakdown of the load balancer inventory, accessible through web UI and reports.
Entuity Load Balancer considers load balancers as devices. From the web UI, you can view data that is directly associated with the load balancer, and data that is collected against its associated objects, e.g. virtual servers, virtual services.
Load balancer data types and associations:
Entuity Load balancer polls every 5 minutes for data for which it retains a history, for example the current number of sessions. Entuity uses the standard data device model to manage different load balancer models, the extent of data collected against each attribute is dependent upon the MIB of each load balancer.
Load balancer summary
The load balancer Summary dashboard indicates the current sessions on the load balancer it was last polled. Entuity polls for current session data every five minutes. It also provides load balancer details including:
- device type, name, model, general info.
- open incidents.
- port summary.
- events over time.
- CPU utilization.
- memory utilization.
- latency.
- SNMP response.
Load balancer resources
The load balancer Resources dashboard displays the performance of processors, memory and powers supplies of the load balancer.
Load balancer advanced
The load balancer Associations dashboards includes details of and links to further information on associated load balancer objects, e.g.:
- local pools.
- real servers.
- virtual services.
- virtual servers.

Local pools
A load balancing pool is a set of devices, servers, that are grouped together to receive and process network traffic. For each pool there is an algorithm that determines the applied load balancing method.
For each local pool, Entuity polls for the local pool Pool Name and Algorithm. Entuity also identifies members of the pool, the load balancer device, real servers, virtual servers and virtual services.
Real Servers
For each real server, Entuity polls for the IP Address and Real Server Name. Entuity also identifies the associated load balancer device, virtual services and assigned local pools.
Virtual Services
For each virtual service, Entuity polls for the IP Address, Service Port and Virtual Service Name. Entuity also identifies the associated load balancer device, real server and assigned local pool.
Virtual Servers
For each virtual server, Entuity polls for the IP Address and Virtual Server Name. Entuity also identifies the associated load balancer device and assigned local pool.
