VIEW STATUS FARM ACTION
This action shows the actual state of backends, clients and connections that are being delivered from the virtual service to the real servers.
The Real Server Status table shows the state of every backend:
Service. It’s the service name associated to the current backend. This is only available for HTTP farm profiles.
Server. It’s the backend identification number within the service if defined.
Address. It’s the real server IP address.
Port. It’s the port number where the real service of the current real server is listening on.
Status. A red dot means that the current real server is down or blacklisted (it could be due to a connection error or due to farmguardian advanced checking), meanwhile a green dot means that the backend is online and delivering connections. A yellow dot means that the backend is in maintenance mode.
Pending Conns. This is the number of pending connections in the system that are on SYN state for the current backend, indepently of farm service.
Established Conns. This is the number of established connections in the system that are on ESTABLISHED state for the current backend, indepently of farm service.
Closed Conns. This is the number of closed connections in the system that are on TIME_WAIT state for the current backend, indepently of farm service.
Clients. It’s the number of clients (unique IP addresses) that are associated with the current backend server. This is only available for TCP farms.
Weight. It’s the weight value established for every backend.
Priority. It’s the priority value established for every backend server. Not available for HTTP farm profiles.
In order to analyze with details the clients, sessions and connections to the backends, you’ve to expand the Client sessions status or Active connections tables to show all this information pressing the buttons “Show client session status table” or “Show active connections table”.
Note that for very high load farms showing this table could slowdown the machine and could be shown a very large table.
Additionally, the datalink farm profiles provides the specific status parameters that are listed below.
Interface. It’s the load balancer network interface connected to the backend.
Rx Total Bytes. Total bytes received for the current backend.
Rx Bytes/sec. Bytes received per seconds for the current backend.
Rx Total Packets. Number of the total received packets.
Rx Packets/sec. Number of the total received packets per second.
Tx Total Bytes. Number of total bytes transmitted.
Tx Bytes/sec. Number of total bytes per second transmitted.
Tx Total Packets. Number of total packets transmitted.
Tx Packets/sec. Number of total packets per second transmitted.
