These graphs display the connections, bytes, bits or packets, depending on choice. The buttons in the top right of the page toggle which values are displayed. The values displayed for the Real Server comprise of the values for all the Virtual Services accessing the Real Server.

If the Real Server has been assigned to more than one Virtual Service, you can view the statistics for each Real Server by Virtual Service by clicking the arrow ( ) to the right of the number in the first column. This expands the view to show the statistics for each Virtual Service on the Real Server.

Note: Because of the way that encrypted services are implemented, it is not possible to view the packet statistics on an encrypted Virtual Service.

VS: The VS column is automatically populated based on a DNS lookup.

RS/VS: This column displays the IP address of the Real Servers and Virtual Services.

Clicking the links in the RS/VS: column displays another screen containing a number of statistics specific to that Real Server or Virtual Service. For further details, refer to the section: Real Server or Virtual Service Statistics.

RS Port: Displays the port of the Real Server.

Status: This shows the status of the Real Server.

Adaptive: This will only be displayed if an adaptive scheduling method has been selected for a Virtual Service. This column will display the adaptive value.

Weight: This will only be displayed if the scheduling method is set to resource based (SDN adaptive) in a Virtual Service. The information which is gathered from the controller determines what the Adaptive value is set to. As the adaptive value goes up, the weight of the Real Server goes down. If all adaptive values are the same, all weights are the same. When the adaptive values are different the weights will change. The weight of the Real Servers determines where traffic is sent. If a Real Server is configured in multiple Virtual Services, two numbers are displayed for the weight - the first shows the average of the current weights over all Virtual Services that the Real Server is configured in. The second shows the number of Virtual Services that the Real Server is configured in. For example, a Weight of 972/2 means that the average weight of a Real Server which is configured in two Virtual Services is 972.

Total Conns: The total number of connections made.

Note: For Layer 4 UDP connections - the connection count always shows as 0.

Last 60 Sec: The total number of connections in the last 60 seconds.

5 Mins: The total number of connections in the last 5 minutes.

30 Mins: The total number of connections in the last 30 minutes.

1 Hour: The total number of connections in the last hour.

Active Conns: The total number of connections that are currently active.

Note: When using ESP, all connections going through the login process are counted as active connections for the Virtual Service. They are not counted as active connections for the Real Server because they are not actual connections to the Real Server. The WUI page displays the number of active connections associated with the Real Servers, while SNMP displays the number of active connections for the Virtual Service. The API returns the same value as displayed in the WUI. Without ESP, these values are identical. When using ESP, the Virtual Service counts can be much higher than the final counts going to the Real Servers, due to the above reason.

Current Rate Conns/sec: The current rate of connections per second.

[%]: The percentage of connections per second.

Conns/sec: A graphical representations of the connections per second.

System Total Conns: This row displays totals for each of the columns.

Clicking RS Totals displays another screen containing total Real Server connection statistics.
