This page contains the following information:
■
DNS TTL —the amount of time, in seconds, that a name server is allowed to cache the
domain information.
■
MX Exchanger —The fully qualified domain name that will be returned if Equalizer
receives a “mail exchanger” request for this geographic cluster. The mail exchanger is
the host responsible for handling email sent to users in the domain.
■
Load balancing method —round trip, adaptive, site load, or site weight. (See
“Configuring a Geographic Cluster’s Load-Balancing Options” on page 89 for
descriptions of these values.)
■
Load balancing response —slowest, slow, medium, fast, or fastest. This value controls
how aggressively Equalizer adjusts the site’s dynamic weights. (See “Adding a
Geographic Cluster” on page 87 for more information about the responsiveness
settings.)
Plotting Geographic Cluster Performance
If Envoy is installed, the Plot Geographic Cluster feature enables you to view a graphical
representation of the performance history for the selected geographic cluster. To plot the
performance history for a geographic cluster:
1. Log into the Equalizer Administration interface with view or edit access.
2. In the left frame, click the name of the geographic cluster whose history you want to
view. The Geographic Cluster Parameters are displayed in the right frame.
3. Select Plot GeoCluster History from the local menu in the Geographic Cluster
Parameters frame. The graphical history for the selected cluster is displayed in the
right frame.
