In general, there are three ESI configuration “phases” on the controller as a part of the solution:
z The first phase configures the ESI ping health-check method, servers, and server groups.The term server here
refers to external server devices—for example, an AVF.
z The second phase configures the redirection policies instructing the controller how to redirect the different
types of traffic to different server groups.
z The final phase configures the ESI syslog parser domains and the rules that interpret and act on syslog
message contents.
Configuring Health-Check Method, Groups, and Servers
To configure the ESI health-check method, servers, and server groups, navigate to the Configuration >
Advanced Services > External Services view on the WebUI.
In the WebUI
To configure a health check profile:

3. Provide the following details:
a. Enter a Profile Name.
b. Frequency (secs)—Indicates how often the controller checks to see if the server is up and running.
Default: 5 seconds.
c. Timeout (secs)—Indicates the number of seconds the controller waits for a response to its health check
query before marking the health check as failed. Default: 2 seconds.
d. Retry count—Is the number of failed health checks after which the controller marks the server as being
down. Default: 2.
4. Click Done when you are finished.
5. To apply the configuration (changes), click Apply. (The configuration will not take effect until you click
Apply.)
