Displaying dynamic server information
When you configure GSLB, the Brocade Virtual ADX creates dynamic real server configurations
based on the IP addresses the GSLB Brocade Virtual ADX receives in response to DNS queries sent
to the real DNS server. These real servers are created for health check purposes only, and do not
play a role in SLB. In the dynamic configurations, the site IP addresses contained in DNS replies are
the names and IP addresses of the real servers. The Brocade Virtual ADX creates internal virtual
servers and then binds the dynamic real servers to the virtual servers based on the application
ports you specify when you add GSLB zones and hosts.
TABLE 11 GSLB resources
Field Description
sites The number of remote sites configured on the GSLB ADX device.
SIs The number of remote site ADX devices configured on the GSLB ADX
device. Each remote site ADX devices is associated with a site. When you
add a remote site ADX device, the GSLB ADX device uses the GSLB
protocol to establish a TCP session with port 182 on the remote ADX
device, for gathering information to use with the GSLB policy.
SIs’ VIPs The number of virtual IP addresses (VIPs) configured on the site ADX
devices that the GSLB ADX device has cached, and the maximum
number of site VIPs the GSLB ADX device can cache.
dns zones The number of zone names currently configured on this GSLB ADX
device and the maximum number that can be configured.
dns hosts The number of host names currently configured on this GSLB ADX device
and the maximum number that can be configured.
health-checks app. The number of applications currently configured on this GSLB ADX
device and the maximum number that can be configured. The ADX
device performs Layer 4 and, if applicable, Layer 7 health checks on
each application.
dns IP addrs. The number of IP addresses the GSLB ADX device has learned from the
DNS server, and the maximum number of DNS records the GSLB ADX
device can store in memory.
static prefixes The number of statically configured prefixes in the GSLB ADX device’s
prefix cache, and the maximum number or statically configured prefixes
the cache can hold.
user geo prefixes The total number of IPv4 or IPv6 user-defined geographic prefixes
currently in the prefix cache, and the maximum number the cache can
hold.
prefix cache The total number of IPv4 or IPv 6 prefixes currently in the prefix cache,
and the maximum number the cache can hold. The prefix entries include
static ones used for geographic information, user-configured prefixes,
and dynamic prefixes created when client queries are received. Dynamic
entries age out when unused.
Health check: VIPs The total number of health checks for VIPs, and the maximum number
supported.
Health check: Reals The total number of health checks for real servers, and the maximum
number supported.
