3. Select Add Site from the local menu. The add site screen opens in the right frame (see Figure
75).

4. Enter the site name, which is a symbolic name that represents this site. For example, the east-coast site
for www.coyotepoint.com might be eastCOAST.
5. Enter the ip, which is the IP address of the site. This is the address of an Equalizer cluster that is
returned if the site is chosen.
6. Enter the agent, which is the IP address of the site monitoring agent. Usually, this is the
external (or Envoy failover) address of the Equalizer at this site.
7. Enter the Static Weight value, which represents the site’s capacity. (This value is similar to a
server’s static weight.) Valid values range between 10 and 200. Use the default of 100 if all
sites are configured similarly; otherwise, adjust higher or lower for sites that have more or less
capacity.
8. Check or clear the Default checkbox. You can designate only one site in a cluster as the default.
• Equalizer returns a peer site’s IP address based on the selected load balancing algorithms.
• Choose the default site 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.
9. Enter the ip in the resource configuration section, which is the IP address of the resource that is
monitored for this site. This must be the same address 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.
10. Enter the port, which is the TCP port number of the resource that is monitored for this site.
11. Enter the ttl value, which is how often the agent should probe the resource. A value of 100
results in the resource’s availability being tested every 100 seconds.
