4. Enter the following information:
5. Specify whether the site is a peer site or the default site by selecting the appropriate
radio button. A peer site’s IP address is returned by Equalizer based on the selected
load balancing algorithms. The default site is chosen if the client’s DNS server did not
respond to ICMP echo requests from any site. This can happen if a firewall blocks
ICMP packets between the client’s DNS and the internet. Only one site in a cluster can
be designated as the default.
6. Click the Add button.
Site Name A symbolic name that represents this site. For example the east-
coast site for
www.coyotepoint.com
might be
eastCOAST
.
Site Address The IP address of the site. This is the address of an Equalizer
cluster that’s returned if the site is chosen.
Keepalive How often the Agent should probe the resource. The default value
of 100 results in the resources availability being tested every 100
seconds.
Static Weight This is a user defined value between 10 and 200 that represents the
site’s capacity. (This value is similar to a server’s static weight.)
Use the default of 100 if all sites are similarly configured, otherwise
adjust higher or lower for sites that have more or less capacity.
Resource Address The IP address of the resource that is monitored for this site.
Usually, this is the same as a configured Equalizer cluster and is
generally the same value as the site address. For example,
east.coyotepoint.com might have resource IP=192.168.0.5
and Port=80 if this cluster were configured on Equalizer.
Port The TCP port number of the resource that is monitored for this
site.
Agent IP Address The IP address of the site monitoring agent. Usually, this is the
external or “Envoy failover” address of the Equalizer at this site.
