This section provides a detailed overview of the statistics for farms and load-balancing services. It includes a table that shows the number of the most recent Established and Pending connections for each LSLB farm.
The table shows the following information about each LSLB farm:
Name: A unique identifier for the farm.
Profile: The type of farm profile, either HTTP or L4xNAT.
Virtual IP: The virtual IP address that receives traffic for the farm.
Virtual Port: The port that the load balancer uses to manage and distribute traffic to the farm.
Established Conns: The number of active connections to the farm. This does not necessarily mean one connection per connected client.
Pending Conns: The number of connections that are waiting to be served by the farm.
Status: The availability status of the farm, indicated by the following colors:
- Green: The farm is running and all backends are UP.
- Red: The farm has stopped.
- Yellow: There are recent changes that need to be applied by restarting the farm.
- Black: The farm is UP, but there are no backends available or they are in maintenance mode.
- Blue: The farm is running, but at least one backend is down.
- Orange: The farm is running, but at least one backend is in maintenance mode.
Actions: This column allows you to view more detailed statistics for the farm.
- Show Backends: This displays all backend servers configured on a particular farm, and the number of client connected to that particular farm.
- Show Graphs: Shows the graphs for the chosen farm.

Name: A unique identifier for the farm.

Virtual IP: The IP address of the real server.
Virtual Port: The port(s) that the real server is listening on.
Established conns: The number of active connections to the real server (only for LSLB farms).
Pending conns: The number of connections that are waiting to be served by the real server (only for LSLB farms).
Status: The health status of the real server, indicated by the following colors:
- Green: The real server is running normally.
- Orange: The real server is in maintenance mode.
- Red: The real server is unreachable.
