Generally, remote ServerIron ADXs in a GSLB configuration are themselves configured with real
servers and virtual servers. The real servers are the actual file servers for which the remote
ServerIron ADX provides load balancing. The virtual servers are the logical IP addresses that are
published instead of the real server IP addresses.

Virtual IPs
The virtual IP addresses (VIPs) configured on the ServerIron ADX.
This information is reported by the site ServerIron ADX.
The letter in parentheses at the end of each address indicates whether
the ServerIron ADX is an active or standby ServerIron ADX for that
address. The letter can be A (active) or S (standby). Unless the
ServerIron ADX is configured along with a partner ServerIron ADX for
Symmetric Server Load Balancing, the value is always A.
If a number appears following the A or S, a host range (the unlimited VIP
feature) is configured on the VIP. The number indicates the number of
hosts in the host range.

NOTE: The GSLB ServerIron ADX does not necessarily provide global
SLB for all the VIPs configured on the site ServerIron ADXs. The
GSLB provides global SLB only for the VIPs that correspond to
the DNS zone names you configure the GSLB ServerIron ADX to
load balance.

Connection Load
The average load at each connection-load sampling interval in the most
recent set of sample intervals.
In the example above, the connection load metric is configured to use six
samples, at 5-second intervals. The sampling intervals and the average
new-connection load at each interval are shown. On this site ServerIron
ADX, the average new-connection load for the last five seconds is 36, the
average new-connection load for the last 10 seconds is 34, the average
new-connection load for the last 15 seconds is 32, the average
new-connection load for the last 20 seconds is 31, and so on. Any time
you enter the command for this site ServerIron ADX, the average load for
the last 30 seconds is shown.
